ABSTRACT:
Catalyst for water dealkylation of oil fractions containing monoalkylated or polyalkylated aromatic hydrocarbons, said catalyst containing at least one metal of group VIII in a proportion of 0.1 to 5% by weight on a carrier, characterized in that said carrier is a zeolite L that can be exchanged with either alkaline cations or polyvalent cations of groups V.sub.b, VI.sub.b and VII.sub.b. The zeolite L can be exchanged with a solution of metals such as lithium, sodium, caesium, chromium, manganese, and rhodium. A method of using the catalyst by contacting the hydrocarbons with the catalyst at a temperature of 400.degree.-600.degree. C., a pressure of 0-80 bars, a space velocity of the hydrocarbon of from 0.1 to 10h.sup.-1, and a water to hydrocarbon mol ratio of 2-20.
