DEVELOPMENT OF MESOPOROUS MEMBRANE MATERIALS FOR CO2 SEPARATION

PDF Version Also Available for Download.

Description

The authors propose to use microporous aluminosilicate as a suitable candidate for CO{sub 2}/N{sub 2} separation because the pore size is less than 10 {angstrom}. If a CO{sub 2} adsorbent is added to the microporous silica, the adsorption of CO{sub 2} can block the passage of N{sub 2} and an effective CO{sub 2}/N{sub 2} separator will be found. It was first demonstrated that microporous silica could be synthesized. The microporous silica was then impregnated with Ba(OH){sub 2}. No adsorption of CO{sub 2} was observed. Alumina must be added to facilitate CO{sub 2} adsorption. However, no microporous aluminosilicates have been shown ... continued below

Alumina must be added to facilitate CO{sub 2} adsorption. However, no microporous aluminosilicates have been shown before. In this six-month study, they developed a process that partially coat alumina on microporous silica. Microporous aluminosilicates were synthesized by the coating process.
