Abstract

High temperature CO 2 separation is effective for the efficient CO 2 reduction. Li 4SiO 4 is one of the high temperature CO 2 adsorbents. In this study, a Li 4SiO 4 thin membrane was developed by using a novel solid state conversion method. Li 4SiO 4 membranes were successfully prepared on a porous alumina substrate at 600 °C conversion from mesoporous silica as silica source. Mesoporous silica was better silica source to obtain Li 4SiO 4 at the low temperature conversion method compared with MFI zeolite, fumed silica and colloidal silica. CO 2/N 2 permselectivity was 0.85 at 600 °C that is higher than the Knudsen diffusion difference. Thus, Li 4SiO 4 layer showed CO 2 permselectivity at 600 °C. It was important to use the mixtures of Li 2CO 3 and K 2CO 3 to fill the pinholes of the Li 4SiO 4 membrane. N 2 permeance through the Li 4SiO 4 membrane decreased to 1.8 × 10 -9 mol m -2 s -1 Pa -1 from 3.9 × 10 -7 mol m -2 s -1 Pa -1 by the addition of the mixtures of Li 2CO 3 and K 2CO 3.
