Abstract: A catalyst for the production of synthesis gas or hydrogen from aqueous methanol by dissociation or steam reforming. The catalyst contains:(A) a noble metal component of one or more elements of the Group VIII of the Periodic Table on an oxide carrier which comprises(B.sub.1) TiO.sub.2 and/or CeO.sub.2, singly or in admixture with other thermo-resistant metal oxides and/or binders or(B.sub.2) TiO.sub.2 and/or CeO.sub.2 on the surface of a preformed, thermo-resistant carrier and(B.sub.3) ZrO.sub.2 or La.sub.2 O.sub.3 in weight concentrations of about 1 to 20% by weight.The concentration of hydrogen or of carbon monoxide may be controlled by monitoring the concentration of steam utilized in the inlet feed.
