| 摘要 |
The invention is a method for reducing the hydrogen cyanide content of a synthesis gas stream including mixing an iron compound with a nitrogen- containing coal feed; gasifying the coal feed in the resulting mixture in an entrained flow gasifier under gasifying conditions thereby producing a gas comprising hydrogen and carbon monoxide and where at least a portion of the nitrogen forms hydrogen cyanide; where the iron compound catalytically converts at least a portion of the nitrogen in the hydrogen cyanide to gaseous molecular nitrogen; and recovering the gas stream having substantially reduced amounts of hydrogen cyanide. |
