摘要： There is disclosed a process for producing a hydrogen-containing gas, which comprises reacting methanol, steam and oxygen in the presence of a catalyst comprising palladium, zinc and at least one metal selected from the group consisting of chromium, gallium, copper, indium, bismuth and platinum. That is to say, the process include the following four aspects: (I) a process which comprises reacting methanol, steam and oxygen in the presence of a catalyst comprising palladium, zinc, and either or both of chromium and gallium; (II) a process which comprises reacting methanol, steam and oxygen in the presence of a catalyst comprising palladium, zinc, copper and chromium; (III) a process which comprises reacting methanol, steam and oxygen in the presence of a catalyst comprising palladium and zinc, or chromium added thereto optionally, and either or both of indium and bismuth; and (IV) a process which comprises reacting methanol, steam and oxygen in the presence of a catalyst comprising zinc oxide, palladium and platinum. The use of the above steam-reforming catalyst having a high activity, high selectivity and sufficient durability makes it possible to produce a hydrogen-containing gas which is composed principally of hydrogen and minimized in CO concentration in an industrially advantageous manner through an auto thermal reformer where methanol, steam and oxygen are reacted with one another.
