Abstract

Aromatics and sulphur are removed from feed-stocks boiling in the gasoline range (i.e. up to 400 DEG F.) and consisting of C4 or higher hydrocarbons containing aromatic hydrocarbons and sulphur compounds, by contacting the feedstock in the presence of hydrogen with a bed containing two catalysts, one consisting essentially of tungsten nickel sulphide and the other consisting essentially of cobalt and molybdenum oxides, either as such or in combined form, on a refractory oxide support, e.g. alumina. The reaction zone is maintained at a temperature of 400-900 DEG F. and a pressure of 50-1,200 psig. Preferably the catalysts are in separate portions of the bed, and are so arranged that the feedstock contacts the tungsten nickel sulphide catalyst first. The cobalt molybdenum catalyst preferably contains 1 to 10% of cobalt oxide, 5 to 40% of molybdenum oxide, and may also contain 0,1 to 6% of fluorine. The ratio of tungsten to nickel in the tungsten-nickel sulphide catalyst is preferably 3:1 to 10:1. The hydrogen sulphide may be removed from the product by stripping with an inert gas.ALSO:Prior to isomerisation, aromatics and sulphur compounds are removed from feedstocks boiling in the gasoline range (i.e. up to 400 DEG F) and consisting of C4 or higher hydrocarbons containing aromatic hydrocarbons and sulphur compounds, by contacting the feedstock in the presence of hydrogen with a bed containing two catalysts, one consisting essentially of tungsten nickel sulphide and the other consisting essentially of cobalt and molybdenum oxides, either as such or in combined form, on a refractory oxide support, e.g. alumina. The reaction zone is maintained at a temperature of 400 DEG F.-900 DEG F. and a pressure of 50-1200 p.s.i.g. Preferably the catalysts are in separate portions of the bed, and are so arranged that the feedstock contacts the tungsten nickel sulphide catalyst first. The cobalt molybdenum catalyst preferably contains 1%-10% of cobalt oxide, 5%-40% of molybdenum oxide, and may also contain 0.1%-6% of fluorine. The ratio of tungsten to nickel in the tungsten-nickel sulphide catalyst is preferably 3 : 1 to 10 : 1. The hydrogen sulphide may be removed from the product by stripping with an inert gas. The so treated desulphurised and dearomaticised feedstock is subjected to isomerisation by contacting it in the presence of hydrogen with a catalyst consisting essentially of an aluminium halide, for example the chloride or bromide, and a hydrogenating metal, which may be selected from Group VI(a) and VIII of the Periodic Table, preferably the platinum group, on a refractory oxide support, preferably alumina which may have been prepared from an alcoholate. The isomerisation is preferably carried out at 50 DEG F.-400 DEG F. and 0-2000 p.s.i.g., and may be effected either in the liquid or the vapour phase.
