Process for reducing concentration of carbon monoxide in hydrogen-containing gas and catalyst used therefor

摘要

There are disclosed a process for effectively reducing a carbon monoxide concentration in a hydrogen-containing gas obtained by reforming methanol or the like, and a catalyst used therefor. In the present invention, carbon monoxide in the hydrogen-containing gas is contacted with oxygen in the presence of a catalyst comprising platinum and at least one metal selected from the group consisting of cobalt, nickel, copper and manganese.
