ABSTRACT
Activated carbon from coconut shell biomass in powder form has been successfully prepared. The purpose of this research is to obtain activated carbon with the optium surface area and time in analyzing the CO2 capture potential. The initial preparation starts from taking the basic ingredients followed by the pre-carbonization process using a furnace with a variation of burning time of 40 minutes, 50 minutes, 60 minutes and 70 minutes. The charcoal produced from the pre-carbon process is neutralized and milled. The sample powder was then carbonized using N2 gas and activated physically using H2O gas at a temperature of 600◦C to 850◦C with variations in holding times of 2 hours, 2.5 hours and 3 hours. Characterization of activated carbon were done using XRD characterization and N2 gas adsorption. The resulting activated carbon is amorphous with a specific surface area of 226,361 m2/g, 475,046 m2/g, and 500,807 m2/g for samples TK-2, TK-2,5 and TK-3. Samples TK-2, TK-2.5 and TK-3 also have a microporous surface area of 164,789 m2/g, 427,459 m2/g, 447,160 m2/g. The adsorption capacity for CO2 capture can be estimated from previous research data, namely TK-2 sample which has an adsorption capacity less than 64.96 mg/g. Samples TK-2.5 and TK-3 have adsorption capacities in the range of 68.14 mg/g – 91.12 mg/g and samples TK-3 have a greater adsorption capacity for CO2 due to the higher surface area of the micropores which have a potential to capture CO2.
Keywords: Activated carbon, coconut shell, CO2 capture, CO2 adsorption capacity
