Abstract
A dehydrogenation catalyst comprises a calcium nickel phosphate prepared as in Specification 634,391, but containing 6 to 12 atoms of calcium per atom of nickel, and a minor proportion, preferably less than 30 per cent, of a chromium oxide, usually the sesquioxide. The chromium oxide may be added at any stage after precipitation of the calcium nickel phosphate either as powder or by addition of a chromium salt, e.g. nitrate or oxalate, which is hydrolysed or decomposed to the oxide. The calcium nickel phosphate precipitate is preferably warmed, e.g. to 50 DEG C. or over, with the mother liquor or water before separation and incorporation of the chromium oxide. The catalyst may be granulated and reactivated as described in Specification 634,391.ALSO:Olefines having at least 4 carbon atoms in the chain containing the olefinic linkage are thermally dehydrogenated as described in Specification 634,391 by passage with steam through a bed of catalyst which consists of calcium nickel phosphate, but containing 6 to 12 atoms of calcium per atom of nickel, and a minor proportion, preferably less than 30 per cent of a chromium oxide, usually the sesquioxide (see Group III) at 500-750 DEG C. The catalyst may be reactivated as described in Specification 634,391 and may be used for the same conversions but has a longer life than the calcium nickel phosphate alone.
