摘要： A process for producing a purified synthesis gas stream from a feed synthesis gas stream comprising hydrogen sulphide, carbonyl sulphide, carbon dioxide, hydrogen cyanide and ammonia besides the main constituents carbon monoxide and hydrogen, the process comprising the steps of : (a) contacting one part of the feed synthesis gas stream with methanol at low temperature and at elevated pressure to remove hydrogen sulphide, carbonyl sulphide, carbon dioxide, hydrogen cyanide and ammonia, thereby obtaining methanol enriched in these compounds and a synthesis gas stream depleted in these compounds; (b) contacting another part of the feed synthesis gas stream with a water gas shift catalyst in the presence of water to react at least part of the carbon monoxide with water, thereby obtaining a shifted synthesis gas stream enriched in hydrogen and in carbon dioxide; (c) contacting the shifted synthesis gas stream with methanol at low temperature and at elevated pressure to remove carbon dioxide, hydrogen sulphide, carbonyl sulphide and ammonia, thereby obtaining solvent enriched in these compounds and a gas stream mainly comprising hydrogen and depleted in carbon dioxide; (d) contacting the synthesis gas stream obtained in step (a) and optionally the gas stream obtained in step (c) with a first solid adsorbent comprising sulphur-impregnated activated carbon and/or activated carbon to remove metals and/or metal carbonyl compounds to obtain a synthesis gas stream depleted in metals and/or metal carbonyl compounds; (e) contacting the synthesis gas stream depleted in metals and/or metal carbonyl compounds in the presence of water with a second solid adsorbent comprising one or more metals or oxides of the metals or combinations thereof, wherein the metals are selected from the group of Ag, Sn, Mo, Fe and Zn at elevated temperature to obtain the purified synthesis gas stream. ® KIPO & WIPO 2009
