Abstract

Catalytic fixation of CO2 to graphite carbon in the temperature range above 500°C was investigated with membrane reactor. The process investigated in this study was consisted of two stage reaction, i. e., decomposition of CH4, into C and H2 and CO2 methanation with formed H2. Thus formed CH4 from CO2 was fed to first bed reactor to decompose to graphite carbon. It became evident that nickel supported on SiO2 was active for both reactions. Since the decomposition of CH4 was drastically increased with the application of membrane reactor system which considered of Pd alloy tube to CH4 decomposition. As a result, about 70% of CO2 can be reduced to graphite carbon at 500°C in this system. Furthermore, the high activity of catalyst was stably sustained over long period.
