Abstract
Abstract This invention relates to a catalyst, to a process for the manufacture thereof and to a process for manufacturing hydrogen by reacting carbon monoxide with water at 150*-550*C in the presence of the above catalyst. This catalyst comprises an active phase consisting of the mixed oxides of (a) copper and (b) a trivalent metal selected from aluminum, chromium, manganese, iron and cobalt, at least 60% by weight of said mixed oxides having a spinel structure. The catalyst is manufactured by admixing the catalyst components in solution with a heat-decomposable complexing organic compound or with a heat-decomposable gelforming compound, the solvent being evaporated thereafter and the mixture being finally roasted at a temperature of at least 200*C.
