Abstract

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.
