Adsorption of Carbon Dioxide on Activated Carbon Derived from Asphaltene & Palm Kernel Shell Mixture

Carbon dioxide (CO2) has been considered as the major influence to the rise of the
temperature globally. Activated carbon is used as the adsorbent for CO2 capture due
to their wide obtainability, high thermal permanence, unresponsive to moisture, large
surface areas and distinctive porosities leading to high adsorption capacities. The aim
of the project is to study the adsorption of CO2 in activated carbon derived from
asphaltene and palm kernel shell (PKS) by mixing both precursors. Activated carbon
is synthesized from the individual precursors as well as mixed precursors of asphaltene
and PKS at different ratio (1:1, 1: 2.5, 1: 5.0 and 1: 7.5) through chemical activation
utilizing potassium hydroxide (KOH) as the activating agent at 600℃ and 60 min.
