Abstract
Abstract Synthesis gas is contacted with an intimate mixture of a carbon monoxide hydrogen reduction catalyst, comprising a methanol synthesis catalyst in combination with a selective class of acidic crystalline aluminosilicate having a silica/alumina ratio greater than 12, a pore dimension greater than about 5 Angstroms to produce hydrocarbon mixtures useful in the manufacture of heating fuels, gasoline, aromatic hydrocarbons, and chemicals intermediates.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
In the process of converting synthesis gas, comprising carbon monoxide and hydrogen, to a hydrocarbon product by contacting such at about 450 to 1000° F with a catalyst comprising as a first component a metal carbon monoxide reduction catalyst and as a second component an acidic crystalline aluminosilicate zeolite having a silica to alumina ratio of at least 12 and a constraint index of about 1 to 12; the improvement which comprises utilizing as said carbon monoxide reducing catalyst component a methanol synthesis catalyst comprising copper or chromium containing catalysts or mixtures thereof in a finely ground form and thereby converting said synthesis gas to substantially only C 1 - C 6 paraffins composed mainly of C 2 - C 4 paraffins.
Claim 2
Dependent Claim
