Abstract

Partly or completely hydrogenated polynuclear hydrocarbons are dehydrogenated to produce aromatic hydrocarbons, having the same number of carbon atoms in the molecule, by treatment above 300 DEG C. and at reduced or atmospheric pressure in presence of a difficultly reducible metal, preferably in the form of oxide or sulphide. The preferred catalysts are 6th group metals, to which activators such as copper, cobalt, or nickel may be added. Specified catalysts are molybdic acid, tungstic acid, tungsten sulphide, magnesium oxide, mixtures of zinc, aluminium, and calcium oxides, mixtures of copper chromite and barium oxide, mixtures of zinc, calcium, and tungsten oxides, mixtures of zinc oxide, magnesium oxide, and molybdic acid, mixtures of molybdic acid and nickel, and alkali metal oxides. The reaction may be effected in presence of inert gases such as hydrogen, nitrogen, carbon dioxide, steam. Examples describe the dehydrogenation of the following hydrocarbons, viz.:--tetrahydronaphthalene, b -phenyl decahydronaphthalene, naphthyl tetrahydro-naphthalene, b -cyclohexyl tetrahydronaphthalene, dicyclohexylbenzenes, b -benzyl tetrahydronaphthalene, cyclohexyldiphenyl, methyl cyclohexylbenzene. Specification 281,298, [Class 1 (i)], is referred to. The Provisional Specification describes also the use of increased pressure in effecting the above-described dehydrogenations.
