Production of Activated Carbon in a Multi-Functional Platform Pilot Plant

Abstract

Activated carbons were produced from coconut shells as  raw materials in a Multi-Functional Platform (MFP) pilot plant using the chemical activation method.. Derived activated carbon named, C1, C2, C3, C4, C5, and C6, based on the activation agent used and the heating rate employed, were compared to a commercial activated carbon based on acceptable parameters. C1, C2, C3, C4, C5 and C6 had relative hardness of 95.67%, 92.67%, 89.67, 91.6%, 90.67% and 93.33% respectively, averaging 92.26%, as compared to 95.6% relative hardness for the commercial activated carbon used. C6 the best performing activated carbon produced (using KOH and heating rate of 7.67 ºC/min) , had an adsorption rate of 188.68 mg Au/ h g, which was higher than the adsorption rate of the commercial activated carbon, which is 185.19 mg Au/ h g. This validates the possibility of activated carbon production commercially in Ghana
