Abstract: A ternary platinum alloy catalyst on a conductive carbon carrier for use in fuel cells is disclosed. For the production of the catalyst, nitrate salts are used as precursors of the alloy components and all alloy components are deposited concurrently on the carbon carrier. This method of procedure yields ageing-stable catalysts with high oxygen mass activity.

Abstract: The invention relates to a process for the selective catalytic hydrogenation of the carbonyl group of aromatic aldehydes of the formula in which X can be a carboxyl group, a methyl group or halogen, to give the corresponding alcohols and methyl compounds. The catalytic hydrogenation is carried out with the addition of a solvent, if appropriate in the presence of organic acids, on a shaped supported catalyst containing a metal from the platinum group on a titanium oxide support in the presence of hydrogen at partial pressure of hydrogen of 5 to 50 bar and temperatures of from 100 to 300@C.

Abstract: THE INVENTION RELATES TO A METHOD FOR THE CONTINUOUS HARDENING OF UNSATURATED FATS, FATTY ACIDS OR FATTY ACID ESTERS AS REACTANTS ON A SHAPED CATALYST IN THE FIXED BED. THE REACTANTS ARE REACTED ON THE CATALYST IN THE PRESENCE OF A MEDIUM OR SOLVENT MIXTURE UNDER SUPERCRITICAL CONDITIONS. THIS LEADS TO CONSIDERABLY IMPROVED ACTIVITIES AND SELECTIVITIES OF THE HARDENING REACTION COMPARED WITH CONVENTIONAL TRICKLE BED HARDENINGS.

Abstract: Moldings are disclosed for use as a catalyst or catalyst support for hydrating olefin, such as ethylene and propylene. The moldings are based on a pyrogenically produced mixed oxide having the following physicochemical parameters:The moldings are produced by homogenizing pyrogenically produced mixed oxide as desired with water and one or more compounds selected from the group of methylcellulose, methylhydroxyethylcellulose, wax, polyethylene glycol, magnesium stearate or aluminium stearate; drying the product at a temperature of 70-150° C.; optionally comminuting to yield a powder; optionally compression molding the powder to yield moldings; and performing heat treatment for a period of 0.5 to 10 hours at a temperature of 400 to 1200° C. Prior to drying, the mixture may also be subjected to kneading and/or shaping processes and extruded.
