Patent number: 4003849Abstract: A heavy gasoline fraction having a relatively low research octane number as for instance a fraction obtained from a cat cracker gasoline is passed over a chlorided alumina catalyst modified by the addition of 0.01 to 5 weight percent lead calculated as PbO. The presence of lead decreases the cracking activity of the catalyst so that it can be operated at a higher temperature which favors increased formation of aromatic hydrocarbons.Type: GrantFiled: June 9, 1975Date of Patent: January 18, 1977Assignee: Phillips Petroleum CompanyInventor: William T.
