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. |
