    Abstract: 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.

    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.

    Abstract: Provided is a ruthenium-based catalyst having from about 1 to 10 wt. % of a ruthenium component and at least about 0.5 wt. % of zinc oxide. In one embodiment of the catalyst, zinc oxide itself serves as a support on which the ruthenium is dispersed. In another embodiment, the ruthenium component and the zinc oxide are dispersed on a refractory oxide support other than zinc oxide. In a process aspect, the ruthenium-based catalyst can serve as a preferential oxidation catalyst in processes for removing carbon monoxide from an input gas stream containing carbon monoxide, hydrogen and oxygen. The invention also provides articles wherein multi-stage preferential oxidation processes for removal of carbon monoxide from hydrogen streams can be conducted.
