Process for conversion of synthesis gas to hydrocarbons using a zeolite-methanol catalyst system

摘要

A process is described for converting synthesis gas containing carbon monoxide and hydrogen to hydrocarbons via methanol as an intermediate, by contacting the synthesis gas with a catalyst system containing a mixture of gallium silicate zeolite catalyst and a methanol catalyst. The process results in reduced amounts of undesirable low carbon number hydrocarbons, e.g., C₄ and lower, undesirable high carbon number hydrocarbons, e.g., C₁₀ and higher, and aromatic hydrocarbons. The process provides higher yields of useful, high octane hydrocarbons boiling in the gasoline range.
