ABSTRACT:
The invention provides a method for producing liquid hydrocarbons by first generating in a pressure swing reformer a synthesis gas stream having a mole ratio of H2:CO greater than 2:1. Then, a portion of the hydrogen is separated to produce a synthesis gas stream having a mole ratio of H2:CO of about 2:1 which steam is then introduced into a hydrocarbon synthesis reactor for conversion to liquid products.
