Abstract
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.
