Abstract
There is disclosed a process for producing a hydrogen-containing gas, which comprises reacting methanol, steam and oxygen in the presence of (1) a catalyst comprising platinum and zinc oxide, wherein the content of the platinum is in the range of 5 to 50% by weight based on the total amount of the platinum and zinc oxide, or (2) a catalyst comprising platinum, zinc oxide and chromium oxide, wherein the atomic ratio of zinc to chromium (zinc/chromium) is in the range of 2 to 30, or (3) a catalyst comprising platinum, zinc oxide and at least one element selected from the group consisting of lead, bismuth and indium. Each of the catalysts has a high activity and is excellent in heat resistance and selectivity to steam-reforming reaction, and accordingly is capable of efficiently producing a reformed gas which is composed principally of hydrogen and is well suited for use in a fuel cell and the like by means of auto thermal reaction reaction, while lowering the concentration of carbon monoxide in a reformed hydrogen-containing gas.
