Abstract

Effective utilization of useful components present in agricultural bio-waste material for CO₂ adsorption is very important. Activated carbons prepared from agricultural bio wastes are very pure with tailor made textural properties which suits for adsorption reactions. Rice husks are subjected to calcination at different temperatures under different atmospheres. Activated carbons and silica will be prepared by different chemical treatment which will be used as supports for carbon dioxide adsorption from environment.The existing Carbon dioxide adsorption methods are environmental unfriendly procedures hence forth researchers are in search for new materials and technologies., that are both ecologically safe, inexpensive and able to fulfill its role with little pre-processing is growing.

New adsorbents prepared from rice husk as low-cost activated carbon using chemical activating reagents, to find out the surface changes occurring in rice husk during activation with phosphoric acid and ammonium hydrogen phosphate. Amine impregnations were carried out on RHPAC and RHAAC activated carbons by using tetra ethylene penta amine (TEPA) for CO₂ adsorption studies. Effect of temperature on adsorption of CO₂ was carried out on all modified activated carbons
