  The mixed gas of CH4 (50%) and CO2 (50%) was fed into the porous compacts of alumina-supported Ni (30 vol%) catalyst heated at 673-973 K. Hydrogen was produced by the reaction of the mixed gas (CH4+CO2→2CO+2H2). A part of produced CO decomposed to CO2 and C (2CO→CO2+C) below 873 K. As a parallel reaction, the decomposition of CH4 occurred in the wide temperature range from 673-973 K. The carbon deposition suppressed the flow of the outlet gas.
