Abstract
The invention is a method for reducing the hydrogen cyanide and ammonia content of a synthesis gas stream exiting a gasifier including mixing an iron-containing compound with a nitrogen-containing coal feed; gasifying the coal feed in the resulting mixture in an entrained flow gasifier have opposed burners under gasifying conditions thereby producing a gas comprising hydrogen and carbon monoxide; and recovering the gas stream having substantially reduced amounts of hydrogen cyanide.
