PROCESS FOR REMOVAL OF HYDROGEN CYANIDE AND AMMONIA FROM SYNTHESIS GAS

摘要

THE INVENTION PROVIDES A PROCESS FOR REMOVAL OF HCN AND NH3 FROM SYNTHESIS GAS, THE PROCESS COMPRISING THE STEPS OF: (A) CONTACTING FEED SYNTHESIS GAS COMPRISING HCN WITH A HCN HYDROLYSIS SORBENT IN THE PRESENCE OF WATER, THEREBY OBTAINING SYNTHESIS GAS COMPRISING NH3; (B) CONTACTING THE SYNTHESIS GAS COMPRISING NH3 WITH AN ACIDIC CATION EXCHANGE RESIN IN THE PRESENCE OF WATER TO REMOVE NH3' THEREBY OBTAINING PURIFIED SYNTHESIS GAS.
