Abstract
Contacting a mixture of carbon monoxide and hydrogen with an intimate mixture of a carbon monoxide reduction catalyst, such as a Fischer-Tropsch catalyst or a methanol synthesis catalyst, and an acidic crystalline aluminosilicate having a pore dimension greater than about 5 Angstroms to produce hydrocarbon mixtures useful in the manufacture of heating fuels, high octane gasoline, aromatic hydrocarbons, and chemicals intermediates.
Claims10
A method for producing hydrocarbons, which comprises:
- contacting synthesis gas having a ratio of hydrogen-to-carbon oxides of from 0.2 to 6.0 with a heterogeneous catalyst at a temperature of from 500.degree. F to 850.degree. F and at a pressure of from 1 atmosphere to 1000 atmospheres, and at a volume hourly space velocity from 500 to 50,000 volumes of gas at standard temperature and pressure per volume of said heterogeneous catalyst said heterogeneous catalyst comprising an intimate mixture of an inorganic carbon monoxide reducing catalyst and a selective acidic crystalline aluminosilicate that has pore diameter greater than about 5 Angstroms;
- a silica-to-alumina ratio of at least 12;
- a constraint index within the range of 1 to 12;
- and, recovering hydrocarbons containing quantities of aromatic hydrocarbons.
