The nature and catalytic properties of a hydrogenation catalyst based on Pd(acac)2 and PH3 are considered.
      
Methanogenesis by a Syntrophomonas wolfei/ Methanospirillum hungatei coculture was inhibited in presence of ethylene and the hydrogenation catalyst Pd-BaSO4.
      
A micromethod for the localization of double bonds in unsaturated fatty acids via ozonolysis employing pyrolytic cleavage of ozonides in the presence of a hydrogenation catalyst is described.
      
Phenanthrene chromium tricarbonyl was used as the hydrogenation catalyst and its activity tested at various concentrations, temperatures and in various solvents.
      
An organic polymer containing a diphenylbenzyl-phosphine functional group, combined with PtCl2 or PdCl2, gives a heterogeneous hydrogenation catalyst which is analogous to the homogeneous catalysts PtCl2(P?3)2 and PdCl2(P?3)2.
      
The poisoning effect of various halogen compounds on a nickel-based hydrogenation catalyst has been investigated.
      
Reactions were carried out at constant temperature, under inert atmosphere (without hydrogen), using an industrial nickelcontaining hydrogenation catalyst.
