    Abstract: 1,150,437. Making combustible gas. BADI. SCHE ANILIN- & SODA-FABRIK A.G. 2 May, 1966 [3 May, 1965; 31 Dec., 1965], No. 19184/66. Heading C5E. Hydrogen-rich gas is produced by cracking vaporizable hydrocarbon mixtures with steam at elevated temperature and at atmospheric or super-atmospheric pressure in two catalytic stages in series. The first catalyst comprises Ni or Co, a carrier material, and at least 0À5% by weight (calculated as oxide) of an alkali metal compound; the second catalyst comprises Ni which contains less than 0À5% by weight (oxide basis) alkali metal compound. Temperatures are 350‹ to 650‹ C. for the first stage and 550‹ to 950‹ C. for the second. Pt or Pd may be included in the first catalyst, and the carrier for both catalysts is magnesium oxide with or without alumina to which zirconium dioxide may be added. Suitable alkali metal compounds are the oxides, hydroxides, nitrates and carbonates and preferred percentages of all catalyst components are given, along with preferred temperatures, pressures, steam ratios and space velocities. The first catalyst may include an hydraulic binder or be calcined. The feed may be gasolines (boiling range 30‹ to 200‹ C,) or higher boiling fractions (up to C 30 ) if desulphurized. Three specific examples are described, in which the second stage follows immediately after the first in a common tube, and the alkali metal is potassium.

    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: A process for the preparation of aralkylamines of the formula where R1 is hydrogen, an aliphatic hydrocarbon radical, a cycloaliphatic radical or alkoxy, R2, R3 and R4 are hydrogen or alkyl, X1, X2, X3 and X4 are hydrogen or alkyl, A is X5, X6, X7, X8, X9 and X10 are hydrogen or alkyl and n is 2, 3 or 4, by reacting a secondary amine with a carbonyl compound in the presence of hydrogen and of a hydrogenation catalyst which comprises palladium, mixed with zinc, cadmium, manganese and/or a rare earth metal oxide, on an inert carrier.
