Separation and Capture of CO2 through A Zeolitic Membrane

Abstract

This paper presents the development and evaluation of a technology for CO2 separation and capture from a mixture of post-combustion gases through a zeolitic membrane. A silicalite-1 membrane was hydrothermally synthesized to selectively separate CO2 from a CO2/N2 mixture and permeation tests were performed on the mixture and the simple gases. The composition and morphology of the silicalite-1 crystals were confirmed by XRD and SEM/EDS. The recovered CO2 was used as raw material for its transformation into inorganic media like carbonates.
