Title: Improvements relating to catalysts and their use
IPC: C10G45/36

Abstract: Organic compounds, for example unsaturated hydrocarbons derived from petroleum are hydrogenated, for example at a temperature of 0 DEG  to 200 DEG  C., with a hydrogenation pressure of 0 to 1000 p.s.i.g., space velocity 0.5 to 10 LHSV, hydrogen treating rate 50 to 2000 SCF/B, using a catalyst comprising nickel or a nickel compound, a base consisting essentially of sepiolite and at least 0.1% weight by weight of the sepiolite of an added alkali metal or alkaline earth metal.  The feedstock may be a gasoline obtained by cracking, for example steam cracking petroleum hydrocarbons at a temperature of from above 593 DEG  to 900 DEG  C. The example relates to hydrogenation of raw steam cracker gasoline.ALSO:A hydrogenation catalyst comprises nickel or a nickel compound, a base consisting essentially of sepiolite and at least 0.1% wt. by weight of the sepiolite of an added alkali metal or alkaline earth metal.  The catalyst may contain from 1% to 50% by weight of total catalyst of nickel.  The sepiolite may be impregnated with an aqueous solution of a nickel salt for example nickel nitrate or an ammonical solution of nickel formate, or dry-milled with nickel formate.  The alkali metal or alkaline earth metal may be added before or after the nickel, and may be used in the form of an hydroxide, a carbonate, bicarbonate, formate, acetate or oxalate.  The catalyst may be calcined to convert the nickel salt to nickel oxide.  The nickel oxide may be reduced to nickel by heating to 150 DEG C. to 600 DEG C. in free-hydrogen containing gas: if nickel formate is used it reduces directly in an inert gas stream. The catalyst may be in the form of granules, pellets or extrudates.
