Abstract

Unsaturated substances are hydrogenated in the presence of a platinum group metal-alumina catalyst prepared according to Specification 735,390, [Group III]. Vapour phase reaction is preferred, at temperatures of from room temperature to 750 DEG F. or above and pressures of atmospheric up to 1000 lbs. per square inch or more. Benzene may be converted to cyclohexane, or ethylbenzene to ethylcyclohexane, at temperatures of 350-700 DEG F. and pressures of 100-500 p.s.i.g. The benzene may be obtained by reforming a C6 petroleum hydrocarbon fraction, containing naphthenes, using a similar platinum-alumina catalyst. The reforming may take place at a pressure at least as great as that of the hydrogenation, hydrogen from the reforming reaction being used for the hydrogenation. Suitable reforming conditions are temperatures of 875-975 DEG F. and pressures of 50-500 p.s.i.g. The product from the reforming or hydrogenation reactions may be purified by fractionation. Examples are given in which benzene and ethylbenzene are converted to cyclohexane and ethylcyclohexane respectively, by continuous flow over the platinum-alumina catalyst mixed with tabular alumina. The conversion of a C6 petroleum hydrocarbon fraction to a high purity benzene is also described. Reference is made also to the hydrogenation of toluene to methylcyclohexane and the hydrogenation of olefines, acids, ketones, aldehydes and nitrogen-containing compounds.ALSO:Unsaturated substances are hydrogenated in the presence of a platinum group metal-alumina catalyst prepared according to Specification 735,390.

Before use in the hydrogenation process, the catalyst may be reduced in hydrogen at 900 DEG F. and atmospheric pressure.
