1.1 General Details Activated carbon is an inert material with porous structure. It is broadly classified on the basis of the following two applications. 1. Those used for adsorption of gases and vapours. (granular and material) 2. Those used for purification of liquids (usually powdered materials) Activated carbon can be manufactured from wood, peat, hard coal and coconut shell. 1.2 Grades Activated Carbon is generally produced in the following grades namely powder, granular pellatised grade and pharmaceutical grade.

Powder grade Used in batch type liquid systems Granular and pelletised grade Used in vapour adsorbing gaseous systems. Pharmaceutical Grades : Most Pharmaceutical Grades of carbon are made

from Pinewood Charcoals, as they have very low ash and acid solubles.

1.3 Physical Properties Porosity Porosity and the pore structure are the most

important characteristics of Activated carbon. Size Size of the micropores is the deciding factor in

selective absorption. Atleast two systems of pores of distinctly different sizes exist in every carbon particle. Macropores (1000 to 2600 Deg A) : Acts as large access ways for diffusion of particles. Micropores (10 to 100 deg A) Contributes towards large surface area which are responsible for absorption action.

Surface area From 200 to 2000 sq.m.per gram, depending upon the method and manner of preparation.

Adsorption behaviour Depending on the process of activation, i.e. steam, as or chemically activated, the Activated Carbon differ in their adsorption behaviour.

2.1 General Details Activated carbon is a unique and effective agent for purification and for isolation and recovery of trace materials. During the last two to three decades, treatment with active carbon has become an important unit process for separations and purifications in the food, pharmaceuticals, sugar, chemical and other processing industries. 2.2 Nature of applications Removal of colour or odour, oxidising chemicals, compounds responsible for foaming, metallic ions which constitute impurity and invisible impurities, To improve product stability and to provide better cystallisation. For recovery of valuable materials, To enhance purity, to improve the appearance of product and to act as barrier to prevent migration of colour bodies. 2.3 Gradewise application Grade

Sector

Powdered Activated carbon Vegetable oils, fats, sugar, water treatment, pharmaceuticals, fine chemicals and food products.

Granular Activated carbon Automotive canisters, air purification, chemical and pharmaceutical industry.

Pelletised Activated carbon Solvent recovery, catalyst application etc �

Activated carbon can be produced from any carbonaceous material, which on activation attain porous structure and consequently a large surface area. Raw materials such as wool, lignite, woods, coconut-shells, agricultural waste like bagasse, rice husk are generally used for the manufacture of Activated carbons. Raw materials having high carbon and low ash content are preferred. Coconut shell has been found to be most suitable raw material for making gas adsorption grade Activated carbon. The shell char is activated with direct steam and fired with liquid fuel in temperature of 1000 to 12000 deg.C in specially designed rotary kiln in controlled conditions to obtain granulated activated carbon. Process flowsheet for Activated carbon from Coconut shells by steam activated process Raw coconut shells (halfs) (Ap. 100 to 150 mm size) Crushing (3 mm to 4 mm size) Carbonisation (500 to 600 deg.C) Cooling Steam activation (1000 to 1200 deg.C)

8.1 Raw Material Requirement 1000 kg of raw coconut shells yield about 100 kgs of vapour grade activated carbon. Utility Fuel 400 litres Power 1240 units 8.2 Raw material availability The coconut shell availability depends upon production level of coconut in the country.
