    Abstract: The present invention relates to a process for preparing alkylaromatics by reacting aromatic compounds with C1-C14-alkanes in the presence of a heterogeneous catalyst, which comprises using as the catalyst a crystalline, micro- and/or mesoporous solid comprising silicon and at least one father element selected from the group consisting of the transition metals and the main group elements gallium and tin, and activating said catalysts by a reducing pretreatment. Furthermore, the present invention relates to a process for preparing alkylarylsulfonates by sulfonating and neutralizing the alkyl aromatic compounds.

    Abstract: A process for the production of essentially unsaturated oligomers of 4-6C alkenes from an alkene or alkene containing hydrocarbon stream at a nickel containing heterogeneous catalyst in an adiabatic reactor at 20-300 [deg]C and 1-100 bar comprises working up a first partial outlet stream to the oligomer and recycling a second partial stream together with fresh alkene to the reactor.

    Abstract: Process for oligomerizing an alkene stream over a solid catalyst comprising sulfur and nickel, in which the oligomerization is carried out in two or more successive catalyst zones and the molar ratio of sulfur to nickel in the first catalyst zone is less than 0.5 and that in the last catalyst zone is 0.5 or more and, in the case of further catalyst zones between the first and last catalyst zones, the molar ratio of sulfur to nickel in each catalyst zone is not less than that in the immediately preceding catalyst zone, based on the main flow direction of the feed stream.

    Abstract: An oligomerization catalyst for olefins having from 2 to 6 carbon atoms is produced by treating aluminum oxide with a nickel compound and a sulfur compound, either simultaneously or firstly with the nickel compound an then with the sulfur compound, and subsequently drying and calcining the resulting catalyst, wherein a molar ratio of sulfur to nickel in the finished catalyst of from 0.25:1 to 0.38:1 is set in this way. The catalyst and its use are also described.
