摘要: 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.

摘要: Trimethylbenzene is selectively prepared by contacting a C.sub.1 to C.sub.4 alkane with magnesium under reaction conditions to produce a reaction product. The reaction product thus produced, is contacted with water or a lower alcohol to promote a protonolysis reaction. The reaction mixture or a fraction thereof from the protonolysis reaction is contacted with a metal containing Y zeolite catalyst under reaction conditions to produce trimethylbenzene.
