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.
Claims4
In the process of converting synthesis gas, comprising carbon monoxide and hydrogen, to a hydrocarbon product by contacting such at about 450 to 1000.degree. 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.sub.1 - C.sub.6 paraffins composed mainly of C.sub.2 - C.sub.4 paraffins.
