    Abstract: Catalysts suitable for hydrogenating organic compounds, essentially containi ng 65 to 80 % nickel calculated as nickel oxide, 10 to 25 % silicon calculated as silicon dioxide, 2 to 10 % zirconium calculate d as zirconium oxide, 0 to 10 % aluminium calculated as aluminium oxide, with the proviso that the sum of the silicon dioxide and al uminium oxide contents is at least 15 %, with the percen tages by weight in relation to the total mass of the catalyst, obtainable by the a ddition of an acid aqueous solution of nickel, ziconium and, if desired, aluminium salts to a basic aqueous solution or suspension of silico n compounds and, if desired, aluminium compounds, the pH of the mixture thus obtained being reduced to at least 6.5 and subsequently adjusted to 7 to 8 by the addition of a further basic so lution, isolation of the solid thus precipitated, drying, shaping and calcinating, i n addition a process for producing the catalysts and the ir use in the production of medicinal white oil, highly pure medicinal paraffins and low-b oiling-point non-aromatic hydrocarbon mixtures.

    Abstract: Fuel composition contains an Otto fuel and a small amount of an Otto fuel additive containing a hydrophobic hydrocarbon residue and a specified polar group. Fuel composition comprises an Otto fuel containing a maximum of 42 vol.% aromatics and a sulfur content of a maximum of 150 wt. ppm, and a small amount of an Otto fuel additive with effective detergency and valve seat antiwear properties. The additive comprises a hydrophobic hydrocarbon residue and a specified polar group selected from: (a) mono- and polyamino groups with up to 6 nitrogen atoms, (b) nitro groups optionally in combination with hydroxyl groups, (c) hydroxyl groups in combination with mono- and polyamino groups, (d) carboxyl groups or their alkali metal or alkaline earth metal salts, (e) sulfonic acid groups or their alkali metal or alkaline earth metal salts, (f) polyoxy 2-4C alkylene groups, (g) carboxylic acid ester groups, (h) groups derived from succinic acid anhydride with hydroxy and/or amino and/or amido and/or imido groups, and (i) groups obtained by Mannich conversion of phenolic hydroxyl groups with aldehydes and mono- and polyamines.
