    摘要： Straight-chain C.sub.2 -C.sub.6 -olefins are oligomerized to their dimers, trimers and tetramers by means of a fixed-bed catalyst, at superatmospheric pressure and at room temperature or elevated temperatures, by a process in which the catalyst used is one which contains, as active components, after deduction of the loss on ignition following heating at 900.degree. C., from 10 to 70% by weight of nickel oxide, calculated as NiO, from 5 to 30% by weight of titanium dioxide or zirconium dioxide, from 0 to 20% by weight of alumina, from 20 to 40% by weight of silica and from 0.01 to 1% by weight of an alkali metal oxide, with the proviso that the contents of the individual components in the catalyst sum to 100% by weight.

    摘要： A process is proposed for preparing acetylene by the Sachsse-Bartholomé process by combustion of a natural gas/oxygen mixture in one or more burners to obtain a cracking gas which is cooled in two or more stages in burner columns, each burner having one or more burner columns assigned thereto, and said cracking gas being quenched with pyrolysis oil in the first cooling stage, to obtain a low boiler fraction comprising benzene, toluene and xylene from the one or more burner columns, which is cooled with direct cooling water and separated in a phase separator into an aqueous phase and an organic phase which comprises benzene, toluene and xylene and is fully or partly introduced to the top of the one or more burner columns as a return stream, wherein the organic phase comprising benzene, toluene and xylene from the phase separator, prior to full or partial recycling to the top of the one or more burner columns, is supplied to a selective hydrogenation over a catalyst which comprises at least one platinum group metal on an inorganic metal oxide as support, comprising 0.05 to 5% by weight of platinum group metal, based on the total weight of the catalyst, and wherein the selective hydrogenation is performed at a pressure in the range from 10 to 70 bar gauge and a temperature in the range from 0 to 100° C.
