摘要:
Ammonia synthesis gas production having a shift reaction stage employing a copper-based catalyst wherein the air supplied to the process is passed through an absorber that removes sulfur and/or halide contaminants, is described. The absorber has a support carrying an absorbent for sulfur compounds and/or absorbent for halide compounds. The removal of the contaminants improves the lifetime e.g. copper-zinc low temperature shift catalysts.
