Claims
- 1. In the process of upgrading hydrocarbon feeds by contacting such with a catalyst comprising a crystalline aluminosilicate zeolite having a silica to alumina ratio of at least about 12 and a constraint index of about 1 to 12, at a temperature of about 500.degree. to 1100.degree.F, a space velocity of about 0.1 to 100 LHSV and a hydrogen to hydrocarbon mole ratio of about 0 to 20; the improvement, whereby eliminating net hydrogen consumption and increasing catalyst cycle life, which comprises: utilizing a catalyst comprising said zeolite having a crystal size of up to about 0.05 micron; and operating said process at a total pressure of up to about 500 psig.
- 2. The improved process claimed in claim 1 carried out at up to about 400 psig with a catalyst comprising ZSM-5 having a crystal size of about 0.02 micron.
- 3. The improved process claimed in claim 1 wherein said feed is a gas oil having a boiling range in the range of about 330.degree. to 750.degree.F.
- 4. The improved process claimed in claim 1 wherein said feed is whole crude.
- 5. The improved process claimed in claim 1 wherein said feed is atmospheric residua.
- 6. The improved process claimed in claim 1 operated under hydrogen pressure.
- 7. The improved process claimed in claim 2 wherein said catalyst comprises a ZSM-5 zeolite having at least one metal selected from the group consisting of zinc, cadmium, palladium and nickel incorporated therewith.
