CO2 Capture Using Amine-impregnated Activated Carbon from Jatropha curcas Shell

This study is aimed at the synthesis and amine functionalization of Jatropha curcas activated carbon. Waste Jatropha curcas shell was used to produce the Jatropha Activated Carbon (JAC) via chemical activation with Potasium hydroxide (KOH). The JAC was modified with triethanolamine (TEA) to produce (JAC-TEA). The performance of both adsorbents in CO 2 capture study was evaluated in a cylindrical glass column equipped with a digital mass balance. The effect of adsorbent dosage (0.5-1.5 g) and temperature (30-60°C) as a function of time was investigated. The results showed that CO 2 adsorption capacities of the adsorbents increase on amine loading and adsorbent dosage (bed height), while the adsorption capacity decreases with increase in temperature. Adsorption capacity of JAC and JAC-TEA were 66 and 78 mg/g respectively.
