Abstract
A process for selective propylation of the benzene content of hydrocarbon mixtures wherein the mixture is brought into contact with propylene in the presence of a crystalline zeolite catalyst having a silica to alumina mole ratio of at least about 12 and a constraint index of from 1 to 12, to produce isopropylbenzene and diisopropylbenzene. The reaction may be carried out at temperatures of from about 100.degree. C. to the critical temperature of the benzene and at pressures ranging between about 10.sup.5 N/m.sup.2 and 6.times.10.sup.6 N/m.sup.2.
Claims8
A process for the selective reaction of benzene relative to toluene in hydrocarbon mixtures comprising benzene, toluene and other aliphatic and aromatic hydrocarbons, said selective conversion process comprising contacting said hydrocarbon mixture with propylene, at a temperature of between about 100.degree. C. and the critical temperature of the benzene reactant at a pressure of between about 10.sup.5 N/m.sup.2 and about 6.times.10.sup.6 N/m.sup.2, in the presence of a selective catalyst comprising ZSM-12 zeolites.
A process for upgrading motor fuels containing benzene therein, said process comprising contacting said motor fuel with propylene, at a temperature of between about 100.degree. C. and the critical temperature of said benzene and a pressure of between about 10.sup.5 N/m.sup.2 and 6.times.10.sup.6 N/m.sup.2, in the presence of a crystalline zeolite comprising ZSM-12.
