Abstract
A process for producing methanol from air-blown gasified coal. A feed gas stream obtained by the coal gasification step is combined with a recycle gas stream and fed to a reactor where carbon oxides are converted to methanol. Exit gas from the reactor is scrubbed to remove carbon monoxide, and the carbon monoxide-free exit gas is then chilled to remove all components except hydrogen. The hydrogen is then combined with the carbon monoxide and used as a recycle stream. The process enables use of an air-blown gasified coal stream while maintaining the nitrogen content in the reactor at an acceptably low level.
