Abstract

Dealkylation of alkyl aromatic hydrocarbons is carried out by passing the hydrocarbons, together with hydrogen, at an elevated temperature of not more than 520 DEG C. over a catalyst comprising a major proportion of a refractory oxide of Groups II, III or IV, a minor proportion of a platinum group metal and a minor proportion of fluorine, said fluorine being added to the oxide already containing the platinum group metal. Conditions specified are temperatures of 400-520 DEG C., pressures of atmospheric-1500 p.s.i.g., space velocities of 0.1-10 v./v./hr. and hydrogen rate of 1000-15000 S.C.F./B. Catalyst specified is platinum/alumina/fluorine. The dealkylation of a kerosene extract is exemplified. Specification 867,990 is referred to.
