• With the greenhouse effect in mind, we have been studying the CO_2 recovery thermal power generation system. In this system, it is necessary to recover CO_2 from LNG reformed fuel gas using a high temperature gas separation system. By a trial calculation of the efficiency of a power generation plant with CO_2 recovery system, it is appeared that membrane separation offered low power and low cost. A homogeneous silica-base membrane was obtained by the advanced sol-gel method with a polymer-hybrid. The gas separation factor of H_2 to CO_2 and the factor of N_2 to CO_2 was larger than 100 at 673K. H_2 permeability was on the order of 10^<-7>mol / m^2・s・Pa order. This performance remained almost constant for 720 hours.
