ABSTRACT '\
Bio-diesel was produced from the trans-ester reaction of vegetable oil and methoxide which is a
reaction involving methanol in the presence of sodium hydroxide (NaOH) as catalyst The
IS called "trans-esterification", the reaction was discovered to be slow but the
mtJroouctlon ofNaOH coupled with increase in temperature of the system accelerated the rate of
The biodiesel produced was separated by using separating funnel processes with
tenme:rature which serves as a catalyst for the reaction. Glycerin soap that was formed from this
~a."'I,lVll was not as hard as other soaps produced from oil, but it was found to be milder,

CHAPTER ONE
l~O INTRODUCTION
The depletion of the world petroleum reserves and reduction in the output of production
and exploration of oil by National and Multinational companies due to economic and political
reasons, necessitated the need to search for alternative energy sources of petroleum based fuel
such as diesel. (Wilfred, 1980). A substitute for andlor additive to fossil diesel fuel which is
derived or extracted from the oils and fats of plant origin is called bio-diesel. (Schumacher ,
1993)
Technically bio-diesel is a vegetable oil methyl ester. It can be produced by trans-
esterification process. Bio-diesel is formed by removing the triglyceride molecule from vegetable
oil (like castor seed oil) in the form of glycerin (soap). Once the glycerin is removed from the oil,
the remaining molecules have characteristics that are similar to petroleum diesel fuel which can
run any type of diesel engine effectively. (Sheehan, 1998) Actually, there are some notable
differences because the bio-diesel molecules are very simple hydrocarbon chain containing
insignificant quantity of sulfur and have no ring molecules or aromatics that are usually
associated with fossil fuel. Bio-diesel is usually made up of approximately 10% oxygen, thus,
making it a naturally "oxygenated" fuel.
A by product from malting bio-diesel is glycerine. In a process called trans-esterification,
waste vegetable oil (WVO) is broken down into esters(bio-diesel)and glycerine. This glycerine
can be filtered to remove any food particles or impurities, and used as industrial degreaser in its - ~
raw form, composted and ,used as a fertilizer or made into bar soap. Bar soap made from your ---------------------
glycerine by-product is excellent for use in the shop because of its de~asing abilities, but can ~~ ----.--, -
also be used as a house hold soap for everyday use. Adding fragrances and dyes will make
household use more appealing to other member of the household.(Terry,2008)
1.1 AIMS AND OBJECTIVES
The aim and objective of this work is to search for an alternative energy source of conventional
diesel and to make use of the by product of the bio diesel for the production of glycerine soap.
Then the aims and objectives of this work includes the following.
(1). To produce castor oil from castor seed.
(2). To fmd a renewable fuel for vehicles.
(3). To initiate or encourage the commercial production ofbio-diesel in Nigeria.
(4). To improve energy self-reliance in rural communities.
(5). To produce glycerine soap from the by product ofbio-diesel.
(6). To encourage the commercial production of glycerine soap in Nigeria.
(7). To be able to produce an effective, glossy soap and also a soap with degreasing ability.
1.2 SCOPE OF STUDY
The production of glycerine soap from the by-product ofbio-diesel which involves+
(1). The extraction of oil from castor seed.
(2). The transeterification of vegetable oil (castor seed oil) to produce bio-diesel 'and its by
product of the bio-diesel.
(3). The production of glycerine soap from the by product of the bio-diesel.
This production of glycerine soap (starting from the extraction of castor oil to the final stage of
producing glycerine soap) consists of batch and continuous processes. The aim of the production
will be achieved through using source of less important to the economy and making it more
useful+

To be able determine the appropriate reaction condition with regards to temperature and catalyst
for the production of suitable bio-diesel.
To be able to determine a suitable method of vegetable oil extraction and the appropriate solvent
for extraction.
To create alternative for Federal Government in producing fuel to produce house for the nation.
To be able to determine appropriate reaction condition with regards to temperature and additives
for the production of suitable glycerine soap from bio-diesel by product.
