Catalytic CO2-MEA Absorption with Solid Chemical MgCO3

Abstract

Solid chemicals MgCO 3 / Mg(OH) 2 (MgCO 3 ) 4˙5 H 2 O were selected to facilitate CO 2 absorption with MEA solvent. The catalytic carbamate formation was confirmed here, to verify heterogeneous catalysis. Since the aqueous hydroxide [OH -] can serve homogeneous catalyst of carbamate formation, MgCO 3 can serve as heterogeneous catalysts/promotors implemented for CO 2 absorption in the amine scrubbing process. The solid MgCO 3 accelerate the CO 2 absorption in MEA solvent properly. These solid chemicals proved to be good candidates for heterogeneous catalytic CO 2 absorption with amine.
