CO2 Capture Using Amine-impregnated Activated Carbon from Jatropha curcas Shell | Chapter 03 | Advances in Applied Science and Technology Vol. 7
A micro porous activated carbon (JAC) was synthesis from Jatropha curcas shell an agricultural waste by chemical activation using 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. Crystallinity, morphological structure and surface functional groups of adsorbents were characterized using X-ray diffraction, Scanning electron microscopy and Fourier Transformed Infra red spectrophotometer respectively, while the surface areas and porosity were d...
