Claims
- 1. In the process for manufacture of liquid hydrocarbon fuels boiling in the gasoline boiling range which comprises converting the oil from tar sands in a first reaction to a gaseous mixture in contact with a methanolsynthesis catalyst in a first reaction of hydrogen and carbon oxides and converting said gaseous mixture to normally liquid hydrocarbons and oxygen-substituted hydrocarbons comprising methanol; the improvement comprising the additional step of contacting at least said oxygen-substituted hydrocarbons including said methanol with a catalytically active aluminosilicate zeolite having a silica to alumina ratio of at least about 12, a constraint index of about 1 to 12 and a crystal density, in the hydrogen form, of not substantially below about 1.6 grams per cubic centimeter at a temperature of about 500.degree. F. to 1000.degree. F., a space velocity of about 0.1 to 50 liquid hourly space velocity, and a pressure of about 1 to 50 atmospheres; and, recovering liquid hydrocarbons.
- 2. A process as claimed in claim 1 wherein said catalytically active aluminosilicate is H-ZSM-5.
- 3. A process as claimed in claim 1 wherein the methanolsynthesis catalyst comprises zinc oxide and said calalytically active aluminosilicate catalyst is H-ZSM-5.
- 4. A process as claimed in claim 1 wherein unconverted synthesis gas is segregated from said first reaction zone effluent stream prior to contacting the remainder of said stream with said catalyst in said second reaction zone.
