    Abstract: Ni-containing sodium molybdate/SiO2 catalysts are used to hydrogenate sulphur-containing mixtures of aldehydes, ketenes and esters such as are obtained in oxo systheses from olefins, CO and H2. In example 3 a feed stream containing inter alia n-butyhaladehyde, isobutyraldehyde, butyl formates and butyene esters is hydrogenated, the aldehydes and substantial portions of the esters being converted to the corresponding butanols.ALSO:In a method of making Ni-containing hydrogenation catalysts, an aqueous solution which is 0.5 to 3 molar in Si and having a ratio Na:Si of 0.7 to 7:1 and a Mo:Si ratio of 0.04 to 0.2:1 which has been prepared from water-glass and sodium molybdate has added to it while stirring such an amount of a 1 to 3 molar Mi salt solution that the amount of Mi added is from 10% by weight more or less equivalent to the amount of sodium contained in the solution and the resultant precipitate is separated from the solution, moulded and reduced in hydrogen at 300 to 500 DEG C. Additionally the catalyst may contain a small quantity of magnesium.

    Abstract: 1,165,064. Refining catalysts. BADISCHE ANILIN-& SODA-FABRIK A.G. 6 Jean., 1967 [8 Jan., 1966], No. 926/67. Heading B1E. [Also in Division C5] A catalyst for the selective hydrofining of pyrolysis gasolines comprises metallic Co and/ or Ni with a small amount of Pd on a carrier having an internal surface area of more than 100 sq. m/g. The carrier may be an active Al 2 O 3 , e.g. boehmite, or a silicate of Mg, Zn, or Al. The content of Co and/or Ni may be from 5-35% and the content of Pd may be 0.01-0.1% by weight.

    Abstract: A process for the continuous selective refining of gasolines which have been obtained by pyrolytic cracking of mineral oils or fractions thereof in the presence of hydrogen at elevated temperature and superatmospheric pressure wherein a catalyst is used which contains metallic cobalt with an addition of copper and/or molybdenum oxide supported on a carrier having a specific surface of 100 m.2/gm. or more. The carrier may be a silicate of zirconium, titanium, magnesium or zinc or mixtures thereof, and/or aluminium oxide. A silicate of cobalt may be used, the silicic acid formed by reduction acting as a carrier. The reaction temperature may be 50-250 DEG C., the catalyst loading 0.5 to 5 kg. of gasoline per litre of catalyst per hour, and the ratio of hydrogen to gasoline should be low but not less than 100 litres/kg.; the pressure is such that most of the gasoline is in the liquid phase.
