Abstract: Process for the catalytic hydrogenation of organic carbonyl compounds containing at least one functional group belonging to the group of aldehydes, ketones, esters and carboxylic acids, whereby said at least one functional group is converted to an alcohol by contacting said carbonyl compound with hydrogen and a hydrogenation catalyst at elevated temperature and pressure as well as a catalyst therefore and a process for producing said catalyst.

Abstract: In a process for hydrotreatment of a gas stream containing both olefins and diolefins as well as organic sulfur compounds, the gas stream is introduced into a pre-treatment reactor, where diolefins are reacted with hydrogen in the presence of a supported Mo-catalyst not containing Co or Ni, whereby the diolefins are substantially converted to olefins. Then the gas stream is introduced into a hydrotreater reactor having a higher inlet temperature than the pre-treatment reactor, in which the gas stream is reacted with hydrogen in the presence of a hydrotreating catalyst under hydrodesulfurisation process conditions, whereby the olefins are substantially converted to paraffins and the organic sulfur compounds are converted to H2S, which is removed by subjecting the hydrotreated gas to a chemisorption or physisorption treatment.

Abstract: The invention relates to the use of thermally-treated supported cobalt catalysts for hydrogenating aromatic nitro compounds, the cobalt catalysts having been prepared by in situ immobilization of a cobalt-amine complex on an inorganic porous support and subsequent pyrolysis, and, in the cobalt-amine complex used, cobalt being present bonded to an aromatic or heterocyclic nitrogen ligand L, the nitrogen ligand being selected so as to form a polyaromatic structure with the cobalt atom.

Abstract: The invention relates to novel complexes and to the use thereof as photosensitizers for generating hydrogen from water.

Abstract: This invention relates to a plasma surface modification process (and a corresponding a system) of a solid object (100) comprising creating plasma (104) by a plasma source (106), application of the plasma (104) to at least a part of a surface (314) of the solid object (100), generating ultrasonic high intensity and high power acoustic waves (102) by at least one ultrasonic high intensity and high power acoustic wave generator (101), wherein the ultrasonic acoustic waves are directed to propagate towards said surface (314) of the object (100) so that a laminar boundary layer (313) of a gas or a mixture of gases (500) flow in contact with said solid object (100) is thinned or destructed for at least a part of said surface (314). In this way, the plasma can more efficiently access and influence the surface of the solid object to be treated by the plasma, which speeds the process time up significantly.
