Abstract
In this study, methane steam reforming in a hydrogen separation membrane reactor was investigated experimentally. Through the permeance measurement experiments, it was disclosed that the silica membrane had H_2 permeance as high as 5×10^<-7> mol m^<-2> s^<-1> Pa^<-1>, which was 5 times as high as CO_2 permeance, under the conditions of temperature of 800℃ and of atmospheric pressure. The methane steam reforming experiments were conducted under the conditions of S/C ratio of 5 and of operation temperature of 800℃. It was clarified that methane conversion of the membrane reactor was smaller than that of the conventional reactor, but H_2 molar fraction of the membrane reactor became larger than that of the conventional reactor.
