Abstract
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 1 ) TiO 2 and/or CeO 2 , singly or in admixture with other thermo-resistant metal oxides and/or binders or (B 2 ) TiO 2 and/or CeO 2 on the surface of a preformed, thermo-resistant carrier and (B 3 ) ZrO 2 or La 2 O 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.
