Abstract: A catalyst for the selective reduction of nitrogen oxides by means of ammonia contains, in addition to titanium oxide as component A), at least one oxide selected from the group comprising W, Si, B, Al, P, Zr, Ba, Y, La and Ce and at least one oxide selected from the group comprising V, Nb, Mo, Fe and Cu as component B), the atomic ratio between the elements of the components A) and B) being 1 : 0.001 to 1. The catalyst is obtainable by kneading reactive titanium oxide of high specific surface area comprising predominantly anatase with the substances comprising component B) or their precursors with the addition of processing agents to give a homogeneous kneaded mass, extruding this, drying the extrudate and calcination in air at 300 - 800 DEG 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: 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.
