摘要： The invention pertains to a multi-stage process for the production of hydrocarbons from syngas comprising hydrogen and carbon monoxide, which comprises the steps of: a) providing a fresh syngas feed to a first stage Fischer-Tropsch reactor and allowing CO and hydrogen to convert into hydrocarbon products at a temperature in the range from 125 to 400° C. and a pressure in the range from 5 to 150 bar absolute, and a gaseous hourly space velocity in the range from 500 to 10000 Nl/l/h; b) feeding the effluent from the first stage reactor to a separation unit; c) removing a gasous effluent stream comprising hydrogen and CO from the separation unit; d) removing one or more other streams comprising hydrocarbon and/or water from the separation unit; e) conveying a first portion of the gaseous effluent stream to a second stage Fischer-Tropsch reactor and allowing CO and hydrogen to convert into hydrocarbon products in the second stage Fischer-Tropsch reactor at a temperature in the range from 125 to 400° C. and a pressure in the range from 5 to 150 bar absolute, and a gaseous hourly space velocity in the range from 500 to 10000 Nl/l/h, whereby the first stage Fischer-Tropsch reactor and the second stage Fischer-Tropsch reactor are separate reactors; f) feeding the effluent from the second stage Fischer-Tropsch reactor to the separation unit; g) removing a second portion of the gaseous effluent stream as off-gas.

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

摘要： 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.
