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.

Abstract: Process for the treatment of liquids consisting mainly of methanol as fuels for mobile or stationary combustion engines or as hydrogen sources for fuel cells, which comprises passing the methanol mixture through a reaction chamber containing a noble metal supported catalyst for the catalytic decomposition or steam reforming of methanol, which is composed of: (A) a noble metal component of one or more elements of Group VIII of the Periodic Table on a carrier material which comprises, (B.sub.1) TiO.sub.2 or CeO.sub.2, singly or in admixture with other refractory metallic oxides and/or binders, or (B.sub.2) TiO.sub.2 or CeO.sub.2, applied to the surface of a preformed refractory carrier.

Abstract: A catalyst for the production of synthesis gas or hydrogen from aqueous methanol by dissociation or steam reforming. The catalyst contains:(A) a metal component of one or more elements of the VIIIb group of the periodic table on a carrier material on the basis:(B.sub.1) of TiO.sub.2 or CeO.sub.2, singly or in admixture with other heat-resistant metal oxides and/or binders or(B.sub.2) of TiO.sub.2, which is introduced onto the surface of a preformed, heat-resistant carrier.Processes utilizing this catalyst allow for the dissociation of methanol for production of synthesis gas, or for the production of hydrogen through steam reforming.Thus, the concentration of hydrogen or of carbon monoxide may be controlled by monitoring the concentration of steam utilized in the inlet feed.

Abstract: Iron oxide-chromium oxide catalyst of increased mechanical strength (lateral crushing strength) for high-temperature water-gas shift reaction. The catalyst contains as an additional component magnesium oxide and/or magnesium spinels in the form of discrete particles.

Abstract: Catalyst for the synthesis of alcohol mixtures containing methanol and higher aliphatic alcohols from CO and H.sub.2, which contains, as an oxide precursor,(a) copper oxide and zinc oxide, which can be transformed into the catalytically active state by reduction with hydrogen;(b) aluminum oxide as a thermostabilizing substance and(c) at least one alkali carbonate or alkali oxide,the oxidic precursor comprising from 20 to 70% of the total volume of pores having a diameter between 14 and 7.5 nm, the alkali content being 13-130.times.10.sup.-6 gram atom alkali metal per gram of the oxidic precursor, and the aluminum oxide component having been obtained from a colloidally dispersed aluminum hydroxide gel or sol.
