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: A formed metal solid-bed catalyst, consisting entirely of catalyst alloy (and possibly promoters) with a total pore vol. of 0.1-0.6 ml/g and with a surface shell 0.1-2.0 mm thick which is activated by complete or partial leaching of an extractable alloy component (I). Also claimed is a process for the production of thE catalyst . Preferably the catalyst metal is nickel, cobalt, copper and/or iron, and component (I) is aluminium, zinc or silicon. The catalyst may also contain up to 15 wt% chromium, iron, cobalt, tantalum, molybdenum and/or titanium as promoters.

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: Hydrogenation of aromatic cpds. of formula (I) or (II) to form cpds. of formula (III) or (IV) by reaction with hydrogen in the presence of a catalyst comprises the use of a solid bed catalyst consisting of at least one Gp. VIII and/or IB metal on a carrier comprising at least one solid acid with a min. acid activity value of 90%. N.B. R1-R8 are not defined in the main claim, but in a dependent claim: R1- R8 = H, alkyl, opt. substd. aryl, opt. substd. phenyl, OH, alkoxy, opt. substd. aryloxy, halo, carboxylic acid or deriv., acyloxy, NO2, sulphonic acid, mercapto, amino, alkylamino or opt. substd. arylamino.
