CARBON MONOXIDE RESISTANT MEMBRANE TO CONTROL H2/CO RATIO OF SYNTHESIS GAS FEED TO FISCHER-TROPSCH UNIT

摘要

An integrated process for making high molecular weight hydrocarbons from a synthesis gas feed to a Fischer-Tropsch unit. A carbon monoxide resistant gold-on-palladium membrane system (membrane system) is used to control the hydrogen-to-carbon monoxide molar ratio of a feed to the Fischer-Tropsch unit. The membrane system is operatively connected between a steam reformer and the Fischer-Tropsch unit. The membrane system receives a synthesis gas stream and provides for the removal of hydrogen from the synthesis gas stream to provide a retentate stream having a desired H2/CO molar ratio that is fed to the Fischer-Tropsch unit.
