How We Teach: Kinetics and Reactor Design

Abstract

The Survey Committee of AIChE’s Education Division surveys departments in the US and

Canada each fall. Kinetics and reactor design or chemical reaction engineering was the topic for

Fall 2020. This paper presents results from 87 different courses representing 80 distinct

institutions as well as discussion from the survey session at the AIChE Annual

Meeting. Results are compared with previous surveys in 2010 and earlier.

Almost all departments still require only one three-credit-hour course in kinetics and reactor

design. Fogler’s textbooks are still the most popular. Over 80% of courses cover topics through

steady-state reactors in depth. Over 60% of courses also cover unsteady non-isothermal reactors

and reaction hazards but with less depth. Over half of the courses responded that more than 50%

of the homework assignments use a computer, which is a substantial increase from the survey in

2010. Exams and individual homework assignments are still the most popular assessments, but

team homework and team projects are increasing. The course is used to assess the achievement

of ABET Student Outcomes 1 and 2 in half of the courses. The majority of departments have

laboratory exercises devoted to kinetics and reactor design in a required course, with experiments

within the kinetics and reactor design courses themselves in over a quarter of departments.

Survey Distribution and Respondents

Each year the AIChE Education Division (EdDiv) Survey Committee surveys departments in the

US and Canada over some portion of the undergraduate curriculum. The survey for 2020

presented in Appendix A was over kinetics and reactor design, also called chemical reaction

engineering. The survey was created in Qualtrics and offered over the web and as a paper

survey. It was distributed to the EdDiv Chairs email list, the EdDiv newsletter, EdDiv social

media, EdDiv virtual community of practice on reactor design courses, the American Society for

Engineering Education Chemical Engineering Division newsletter, and individual emails to

chairs of Canadian chemical engineering departments in September and October 2020. The

survey link was also posted during sessions at the AIChE Annual Meeting.

The 80 responding institutions are listed in Appendix B; thank you for your contributions.

Three institutions have replies from two different professors who both teach the course. Not all

questions were answered by all respondents. Comparing the survey respondents to the US and

Canadian institutions overall is more difficult this year as ASEE has changed the data reported in

their Engineering by the Numbers [1]. Graduating class sizes for the top 50 US chemical

engineering programs by size are presented, and demographics are given only by all 160 US

programs in aggregate. Twenty-two of the top 50 US programs by graduating class size

responded to the survey. Top 50 by class size US institutions are nearly equally represented in

the US (50 of 160, 31%) and our survey respondents (22 of 80, 28%). Figure 1 compares the

graduating class size for our respondents in the top 50 to those top 50 US institutions by class

size. Our respondents in this group do have larger class sizes by 8 students on average.

Page 4: How We Teach: Kinetics and Reactor Design

Figure 1. Graduating class sizes of the top 50 chemical engineering programs in the US by class

size compared with survey-responding institutions within the top 50 by size. Note that the range

is from 80 to 260 students.

Of the 80 distinct institutions, 92.5% (74) use semesters and 7.5% use trimesters. Institutions in

the United States were 75 of the 80 responding institutions (93.5%), and 5 were Canadian, which

is an increase from the 2019 EdDiv survey on the first year experience [2].

The vast majority of the 80 distinct departments required one three-credit-hour course, which has

changed little over the surveys from 1974, 1984, 1991, and 2010 [3]. One course is required at

76 institutions, and four institutions require two courses. Of the four institutions requiring two

courses, two are Canadian and one uses trimesters. For credit hours, 59 institutions (74%) have a

3-credit-hour course, and 13 (16%) have a 4-credit-hour course. Only two of the 4-credit-hour

courses are offered at institutions on the quarter system. The range was from 0.5 to 36 credit

hours, which may be credit units or other accounting systems.

Although the survey did not include the timing of the kinetics and reactor design course in the

curriculum, the majority of the attendees at the survey discussion session at the

2020 AIChE Annual Meeting plan the course for the second semester of the junior year.

Fogler’s Elements [4] and Essentials of Chemical Reaction Engineering [5] textbooks are still

the most popular, used by 60% of the 85 reporting courses, as shown in Figure 2. Fogler’s

textbooks were also the most commonly used in the 1991 and 2010 surveys [6]. A sixth edition

of the Folger Elements textbook was released in Fall 2020 but was not captured in this survey.

The “Other” category includes books by Hill, Froment, Hayes, and Davis as well as others not

further described. The websites used most often in 63 responding courses are the textbook

website and the course’s learning management system (Figure 3). Other resources not

specifically listed in the figure include Chemical Safety Board videos [7], SACHE materials [8],

CACHE learning modules [9], Concept Warehouse [10], and Wolfram Alpha.

We asked respondents about the topics covered in their courses, using the chapter titles from

Fogler’s Elements book and categories of “not covered’, “some”, and “in depth”. In the 84

courses reporting, early topics in Fogler’s text, through isothermal reactors, are nearly

universally covered in depth (Figure 4). Multiple reactions are covered at least some at all

reporting institutions.

Of later topics in Fogler’s text, steady state nonisothermal reactor design and reactivity hazards

are covered at least some at 90% and 70% in 84 reporting courses, respectively (Figure 5). The

coverage of reactivity hazards in 2020 is a huge shift as it was not mentioned as a chapter topic

in the 2010 survey. Residence time distributions, nonideal reactor models, membrane reactors,

and absolute reaction rates are not covered in over 50% of the courses.

Differential equations is a pre-requisite for 95% of the 81 reporting courses, as shown in Figure

6. Fluids, heat transfer, and mass transfer courses are pre-requisites for over half of the

courses. The “other” category includes many reports of thermodynamics and material & energy

balances courses. The percentage of courses requiring differential equations is unchanged since

2010, but about 10% fewer courses are requiring fluids, heat transfer, and mass transfer

courses. About 10% more courses require a numerical methods course than in 2010 [3].

Figure 6. Percentage of 81 courses requiring courses as pre-requisites

Upper-level courses are frequently used to assess ABET outcomes, and Figure 7 shows that

kinetics and reactor design is no exception. The course is used in over half of the ABET-

accredited departments to assess Student Outcome 1: solve complex engineering problems (72

courses reporting). Figure 7 also shows that 50% of the kinetics and reactor design courses

assess Student Outcome 2: apply engineering design. The course is also used to contribute to

the development of Outcome 6: experimentation and analysis in over half of the courses. The

ABET student outcomes have changed since 2010 which makes comparisons difficult, but over

50% of departments used this course to assess old outcomes a, c, e, and k. Outcomes a, e, and k

are related to the current outcome 1, and c, h, and k are related to outcome 2, showing that little

has shifted with the kinetics and reactor design course regarding ABET assessments over the

decade.

skills in at least two-thirds of the courses. Over half of the courses contribute to Skill 9:

engineering impact on society & environment.

Teaching assistants (TAs) play a small role in the kinetics and reactor design course. Of the 85

courses reporting, 11% say that the teaching assistant teaches some. Of those nine courses, the

TA teaches 5% or less of the class time in eight of the courses. In one course, the TA teaches

between 10 – 20% of the class time.

Computer Use and Software Packages

The kinetics and reactor design course needs computational solutions in modern teaching, as

seen in Figure 9 with the fraction of assignments requiring the use of a computer. When the

categories for 50% or more of the assignments are summed, more than 50% of the courses

require more than 50% of the assignments be completed with a computer. More than a quarter of

the courses require computer use on at least 70% of the assignments. In 2010 the highest

category reported was more than 50% of homework assignments, which was 24% of

departments. More courses are requiring the use of computers on more assignments since 2010.

Figure 9. Percentage of 85 courses reporting the fraction of assignments which require the use of

computers

We also asked about the computer programs used. Survey respondents were able to choose more

than one software package. Spreadsheets and MATLAB are used in nearly two-thirds of the 85

courses reporting (Figure 10). This represents a shift from spreadsheets to MATLAB which

were at 75% and 50% of departments, respectively, in 2010. Polymath is a close second in 45%

of the courses and is unchanged from 2010. We also asked about where different software

packages were used – in lectures or in projects (Figure 11). Thirteen courses described using

software in lectures, and 11 courses use software in projects. Respondents could again choose

multiple packages. MATLAB is used in over half of the courses for lectures but was used much

less frequently for projects. Polymath is used in about 30% of the courses for lectures.

Polymath, Excel, and Aspen are used in about 30% of projects. Although faculty at the survey

discussion session at the 2020 AIChE Annual Meeting like the ease of Polymath’s graphical user

interface to solve problems without programming knowledge, they were concerned about

continued support for the program. Some anticipate moving (or have already moved) to

Python for numerical analysis.

Assessment and Course Activities

Individual homework and exams were used in over 90% of the courses, making them by far

the most popular assessments in the 85 reporting courses (Figure 12). Respondents were able

to choose more than one assessment. The popularity of exams and individual home is

unchanged from 2010 [3]. Individual projects appear in about 10% fewer courses than in 2010 but have

been replaced with correspondingly more team projects. Team homework did not appear in the

2010 survey but is used in 25% of the courses reporting this year.

Figure 12. Percentage of 85 courses reporting the use of particular assessments

Most kinetics and reactor design course class time is used in lectures. The average over the 79

reporting courses is 60% of class time spent on lectures. About 95% of class time was accounted

for by the items shown in Figure 13. Recitation/discussion and flipped classroom activities took

up the next largest parts of class time at 13% and 9% on average. One school teaches primarily

with case studies, using 70% of class time. Example problems was marked by only four schools,

but they use example problems for 20 – 40% of their class time. The class activities that

complete the remaining 5% of class time and are not shown in Figure 13 are example problems,

demonstrations/experiments, posters/oral presentations, quizzes/exams, debates, guest speakers,

and plant/site visits.

courses with labs was 30% in 1974 but dropped since then, so we have almost returned to 1970’s

levels.

Figure 15. Percentage of departments with labs in kinetics and reactor design in the specified

courses

In 75 experiments that were described, rate laws, single reactor performance, and kinetic

parameters are each the topic of more than half of the experiments (Figure 16). More than one

topic could be chosen for each experiment. Catalysis is the topic of a third of the experiments.

The “Other” category includes scale-up, mass transfer, bioreactors, fermentation, non-ideal

reactors, and process control. The three major classes of reactor systems are nearly equally

represented in experiments: batch, tubular, and continuously-stirred tank reactors (CSTR)

(Figure 17). The “Other” types of reactor systems are fixed bed, fuel cell, semi-batch, and

differential. Physical experiments make up 80% of the experiments described (Figure 18). The

wide range of reaction categories used in 57 laboratory experiments are given in Figure 19.

Saponification/esterification, petrochemical, and decolorization experiments are the most

popular, but each accounts for under a third of the experiments. Simplifying chemical inventory

by studying the same reaction in different experiments within the department is common. The

most common petrochemical reactions are oxidation of CO, hydrogenation/dehydrogenation, and

alkylation.

Effective Teaching Methods

One open-ended question allowed faculty to describe the unique features of the course as they

teach it. One theme that emerged from responses is an emphasis on teaching. Faculty mentioned

six different areas that they emphasize in teaching:

• Problem-solving approaches,

• Deriving mass and energy balances,

• Deriving rate equations,

• Rawlings-Ekerdt approach,

• Incorporating materials from prior chemical engineering coursework, and

• Incorporating visuals (schematics, graphs, and illustrations).

Another theme that emerged from the free-response to unique aspects of this course is

incorporating topics throughout the semester. Topics that were mentioned include

• Safety,

• Kinetics and reactor design impact on climate change and environment,

• Biological reactor engineering,

• Case studies,

• Environmental remediation, bioremediation, fermentation,

• Safety, social justice, ethics,

• Mass transfer,

• Controls and safety, and

• Industrial examples

Two faculty mentioned unique assignments. The first one was a MEME assignment, in which

the students create a MEME plus an in-depth discussion of the topic and a quiz for the class.

Another professor requires the students to develop an outreach activity for K-12 students on a

course topic.

One survey question asked respondents to describe their roles in the class. The 64 responses

were categorized as in Figure 20; some responses fell into more than one category. “Sage on the

stage” responses emphasized terms such as instructor, teach, and tell. “Guide on the side”

responses included facilitate, mentor, supporter, or guide. Slightly more than half of the faculty

described their roles as being a “guide on the side” for the students. Faculty who help students

prepare for the future in this course are considering both future courses (design) and careers in

industry and research.

Figure 20. Categorized responses to "Describe your role in the class"

Several faculty mentioned fun analogies as being particularly effective explanations. Some

analogies are listed below.

• Making tea for rate law k calculation

• PFR as a batch reactor on a conveyor belt

• Heterogeneously catalyzed reactions: tug-of-war between mass transfer and reaction

• Armageddon movie as heterogeneous catalysis

• Grandma and the motorcycle for rate-limiting step

• Rate-limiting step of wrapping presents

• Rolling dice for rate laws

Demonstrations were also listed as particularly effective explanations.

• Skittles in a bowl diffusion experiment

• Making grilled cheese sandwiches to illustrate stoichiometric tables

Quite a few faculty intend to continue changes they made in Spring 2020 due to COVID-19.

Twenty-five respondents intend to continue use of pre-recorded lectures. “On-line resources

developed in this circumstances will stay for support and further development, as they have

proved to be efficient and students were adapted.” Another five respondents intend to continue

use of virtual office hours, as “remote office hours (via Webex, Zoom, etc.) are useful to reach

students in the evenings or on weekends.”

Course Challenges

When asked about particular challenges in teaching this course, challenges with student

preparation/student capabilities (or lack thereof), the availability of resources such as problem-

based learning activities, and course/curriculum challenges were identified. Common areas of

student weakness are mentioned below, with those weaknesses appearing in the 2010 survey

marked with *:

• *Math software,

• Programming,

• *Differential equation formulations,

• *Analytical solutions when possible,

• Numerical methods when needed,

• *Chemistry recollection,

• Thermodynamics recollection,

• Comprehension of mixing, and

• Mass transfer/fluid mechanics application

Most often students struggled with the knowledge and conceptual integration required to

understand and analyze chemical reactors and chemical reactor design. Other challenges in

teaching kinetics and reactor design include novel problem creation to avoid academic

misconduct, creating compelling practice and homework submissions, lack of authentic

problems, incorporating new technologies, timing of related lab experiences, and developing

conceptual learning versus algorithmic solutions.

Conclusions

Most of the changes for the kinetics and reactor design course within the past decade are

associated with increasing computer use to solve problems. Another big change is the explicit

inclusion of reactivity hazards in over 70% of the courses. Assessments have shifted slightly

towards more teamwork in both homework and projects. Most other changes in the course have

been slight, on the order of 10% of courses.
