Utilization of ionic liquids for the enrichment of biogas

Abstract

This article discusses the dependence of biogas composition on organic feed material. High amounts of CO2 decrease the caloriﬁc value of biogas. Several technologies are reviewed which can be used to increase the caloriﬁc value. Special emphasis is laid on ionic liquids as a new absorbing material. ILs have a number of advantages due to their unique properties such as: low melting point, high thermal conductivity, no ﬂammability, high decomposition temperature and low volatility. It has been proven that ionic liquids are compounds which act selectively, forming a stable liquid membrane. Furthermore, the structure of ILs can be modiﬁed in order to improve their CO2 absorption capacity by physical interaction and even by chemisorption.
