Activated Carbon Supported Amine Functionalized Ionic Liquids for CO2 Sorption

Ionic liquids (ILs) have been proven to produce promising results in CO2 capture. However, ILs suffer the problem of having high viscosities which limit the application. Impregnation of ILs into porous solid support may be an alternative to overcome this problem. In this study, the wet impregnation...

Description
Summary:Ionic liquids (ILs) have been proven to produce promising results in CO2 capture. However, ILs suffer the problem of having high viscosities which limit the application. Impregnation of ILs into porous solid support may be an alternative to overcome this problem. In this study, the wet impregnation method was used and this was confirmed by surface area, pore volume and pore size before and after impregnation. Activated carbon impregnated with 10wt% of [hmim][NTf2], [vbtma][gly] and poly[vbtma][gly] were prepared to study the CO2 sorption. The results showed that activated carbon impregnated with [vbtma][gly] gives higher CO2 sorption with 19.91 mmol/g at 20 bar. Therefore, a series of activated carbon impregnated with l0wt%, 20wt% and 30wt% of [vbtma][gly] were prepared to study the optimum composition of [vbtma][gly] for CO2 sorption. The CO2 sorption studied showed the optimization occurred at 20wt% of poly[vbtma][gly] and CO2 uptake increased with pressure increased.
