Abstract
A process for the hydrogenation of aromatic hydrocarbons contained in a hydrocarbonaceous oil feed is provided in which the feed is contacted with hydrogen in a substantially sulfur-free environment in the presence of a catalyst comprising a Group VIII noble metal component, such as palladium, deposited on a steamed support such as steamed tungsten oxide composited with alumina.
Claims12
A process for the hydrogenation of aromatic hydrocarbons, which comprises:
- contacting said aromatic hydrocarbons, at hydrogenation conditions, in a hydrogenation zone in the presence of added hydrogen and the substantial absence of an inorganic sulfur compound, with a catalyst comprising (a) a noble metal component of Group VIII of the Periodic Table of Elements, and (b) a steamed support comprising a transition metal oxide composited with a non-zeolitic inorganic oxide, said transition metal oxide being selected from the group consisting of tungsten oxide, niobium oxide and mixtures thereof, said support having been steamed at a temperature of 500.degree. to 1200.degree. C.
