ABSTRACT:
A process for producing a purified synthesis gas stream from a contaminated feed synthesis gas stream is disclosed. A part of the feed synthesis gas stream is subjected to a water gas shift step. The water gas shift step is used in combination with bulk contaminant removal followed by polishing to thereby remove the contaminants from the synthesis gas stream so as to provide the purified synthesis gas stream having a desired low level of contaminants.
