Impact of Amine Functional Group on Rice Husk Ash Samples Derived From Rice Husk: A Comparative Co2 Adsortion Studies

Abstract

      Surface modifications with amine functionalized materials have greater ability for the capture of CO₂. In general, porous materials are widely applicable for CO₂ adsorption due to their high surface area and easily susceptible nature for the surface modification by amine functional groups. The main objective of this work presented is to develop a Nano porous solid adsorbent which can serve as a best adsorbent for CO2. Rice husk ash samples prepared at different temperatures under N₂+steam atmospheres are impregnated with Mono Ethyl Amine (MEA), Di Ethyl Amine (DEA) and Poly Ethylene Imine (PEI) in 5, 10, 15, 20 and 25 wt.%. All these samples are subjected to Characterization studies and CO2 adsorption studies.
