    Abstract: 1,129,977. Hydrogen by shift reaction. BADISCHE ANILIN- & SODA-FABRIK A.G. 9 Feb., 1966 [10 Feb., 1965], No. 5620/66. Heading C1A. [Also in Division B1] A gas mixture consisting of 9À4% CO, 36À7% H 2 , 0À4% N 2 and 53À5% steam is passed at a space velocity of 6000 cu. m. of wet gas per c.c. of catalyst per hour over a specially prepared catalyst comprising Cu, Al, Cr and Mn at 220‹ C. 98% of the CO is converted to CO 2 with concurrent production of hydrogen. In an alternative procedure a gas mixture consisting of 2À52% CO, 71À95% H 2 , 2À34% CO 2 and 23À2% of inert gas has added to it 0À68 cu. m. (S.T.P.) of steam per cu. m. of dry gas. The whole is passed at 10 atmospheres gauge and 185‹ C. over 5 x 5 mm. pellets of catalyst as above. Only 0À034% CO remains unchanged.

    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 mixture of 80 cu. m. (S.T.P.) per hour of methane and 160 cu m. (S.T.P.) per hour of steam is passed through a vertical cylindrical cracking reactor at 800 DEG C. containing 100 litres of catalyst prepared by shaping NiO and MgO, calcining at 1200 DEG C. or more such that all or the major portion of NiO is combined as mixed crystals of NiO and MgO. The cracked gas is cooled to room temperature, steam thereby being removed by condensation and the gaseous product has the composition CO2, 7%; CO, 15%; H2, 77%; CH4, 0.2%; and N2, 0.8%.ALSO:In the preparation of cracking catalysts, a mixture of NiO and MgO is shaped and then converted by calcination at a temperature of more than 1200 DEG C. into a form in which all or the major portion of the NiO is combined as mixed crystals of NiO and MgO. Additionally the catalysts may contain one or more of A12O3, SiO2 ZrO2, Fe2O3 and CaO. Before use as cracking catalysts the compositions may be subjected to reduction. Hollow catalysts in tablet form of specified size are described in Example 2.
