Abstract

This paper presents an easy way to prepare carbon dioxide sorbent by using commercially available fumed silica particles (AEROSIL). AEROSIL was impregnated with various concentration of polyethyleneimine (PEI) in methanol and $CO_2$ capture ability was analyzed by thermo gravity analysis (TGA). The $CO_2$ adsorption capacity of 50 wt% PEI-impregnated AEROSIL was 126.2 mg/g-sorbent at $75^{\circ}C$ and this capacity was substantially higher than that of the mesoporous silica such as HMS (101.0 mg/g-sorbent) and MSU-J (66.1 mg/g-sorbent).
