    Abstract: PROBLEM TO BE SOLVED: To provide a highly dispersed active component and to ensure high sintering stability and aggregation stability by applying a catalytically active metal to a support modified in the form of a chloride-free dissolved amine complex, acetylacetonate complex or allyl complex. SOLUTION: An inner support material such as granular SiO2 is pretreated by heating before coating with a modifier preferably used in the form of an alkoxide. The inner support material is then impregnated into a liquid phase, e.g. in an aqueous or organic phase or into a gaseous phase, e.g. by chemical vapor deposition. The resulting support material modified in the form of a chloride-free amine complex, acetylacetonate complex or allyl complex is optionally hydrolyzed, dried and calcined. A catalytically active metal such as Pd or Pt is applied to the modified support material by impregnation or ion exchange and then drying and optional calcination are carried out.

    Abstract: PROBLEM TO BE SOLVED: To provide a process for the production of an olefin as a set of products by a 4C stream of a steam cracker or a refining apparatus. SOLUTION: This olefin production process comprises (A) a step to perform extractive distillation of butadiene from a 4C stream optionally using a butadiene-selective solvent, (B) a step to selectively hydrogenate butadiene and acetylene impurities in the 4C stream supplied from a steam cracker or a refiner or a stream of the step A and simultaneously isomerize at least a part of 1-butene to 2-butene, (C) a step to remove i-butene from the 4C stream and obtain an ether, (D) a step to remove oxygen-containing impurities from the 4C stream using an adsorbing material and (E) a step to perform the metathesis of butene in the 4C stream in two stages.

    Abstract: The present invention relates to a method for producing mixtures of monoolefinic C5-mononitriles with non-conjugated C=C- and CN-bonding by catalytic hydrocyanuration of a 1,3-butadiene-containing hydrocarbon mixture, which is characterized in that initially the proportion of those constituents impairing catalytic hydrocyanuration is reduced in the hydrocarbon mixture, and the mixture obtained thereby is subsequently catalytically hydrocyanurated.

    Abstract: Catalyst contains a catalytically active metal in the form of its chloride-free dissolved amine complexes, aetylacetonate or allyl complexes on a modified carrier. An Independent claim is also included for a process for the production of the catalyst comprising: (a) thermally treating the carrier material; (b) impregnating the carrier material with a modifier in the gas or liquid phase; (c) optionally hydrolyzing the modified carrier material at 20-200 degrees C in O2 or in air or in a H2O-containing gas stream; (d) optionally drying at 100-500 degrees C; (e) optionally calcining at 200-1000 degrees C; (f) applying the catalytically active metal by impregnating or ion exchange; (g) drying at 20-500 degrees C; and (h) optionally calcining at up to 1000 degrees C.
