    Abstract: PROBLEM TO BE SOLVED: To hydrogenate an arom. hydrocarbon at a high efficiency at medium temp., pressure, and catalyst space velocity without substantial detriment to the octane number by hydrogenating a feed stream contg. the arom. hydrocarbon with an Ni-contg. precipitation-method catalyst at specified temp., pressure, and catalyst space velocity in the presence of free H2 . SOLUTION: A feed stream, pref. a reformate stream, contg. an arom. hydrocarbon (e.g. benzene) pref. in a concn. of 2-30 wt.% is hydrogenated with an Ni-contg. precipitation-method catalyst at a temp. of 30-300 deg.C, pref. 70-200 deg.C, under a pressure of 20-80 bar, pref. 25-40 bar, and at a catalyst space velocity of 1-6 kg/(l×h), pref. 2-4 kg/(l×h), in the presence of free H2 . Pref., the catalyst comprises, in terms of oxides, 65-80 wt.% Ni, 10-25 wt.% Si, 2-10 wt.% Zr, 0-10 wt.% Al, and at least 15 wt.% (Si+Al).

    Abstract: PCT No. PCT/EP94/03838 Sec. 371 Date May 16, 1996 Sec. 102(e) Date May 16, 1996 PCT Filed Nov. 21, 1994 PCT Pub. No. WO95/14647 PCT Pub. Date Jun. 1, 1995Straight-chain C2-C6-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 DEG 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.

    Abstract: A method for the selective hydrogenation of butadiene to butenes in the liquid or trickle phase on firmly arranged noble metal supported catalysts, in which a C4 stream rich in butadiene having a butadiene content of 20 to 80 % by weight, relative to the C4 stream, is hydrogenated in two reaction zones connected in series such that the hydrogenation product of the first reaction zone contains 0.1 to 20 % by weight and the hydrogenation product of the second reaction zone contains 0.005 to 1 % by weight of residual butadiene relative to the C4 stream, with the proviso that the butadiene content of the hydrogenation product from the second reaction zone is reduced by at least the factor 5 compared to the butadiene content of the hydrogenation product from the first reaction zone.

    Abstract: Catalyst suitable for hydrogenation of organic cpds., comprises (all based on total wt. of catalyst); (a) 80 wt.% nickel (calculated as nickel oxide); (b) 10-25 wt.% of silicon (calculated as zirconium oxide; and (d) 0-10 wt.% of aluminium (calculated as aluminium oxide). The amt. of silicon dioxide and aluminium oxide is at least 15 wt.%. The catalyst is prepd. by; (2) adding an acidic aq. soln. of nickel-, zirconium- and opt. aluminium salts to a basic aq. soln. or suspension of silicon cpds. (and opt. aluminium cpds.), so that the pH of the resulting mixt. drops to at least 6.5; (2) adding a further basic soln. to bring the pH to 7-8; and (3) isolating the pptd. solid, which is then dried, formed and calcined.
