Abstract
An intergrated recycle process for the production of methanol from a process synthesis gas produced by hydrogasification of a condensed carbonaceous feedstock to produce a process gas which is reacted in a steam pyrolysis reactor with additional natural gas and steam to produce said synthesis gas containing hydrogen and carbon monoxide in more than a 2:1 molar ratio which constituents in turn are reacted in a methanol synthesis reactor to produce methanol. The important factor in this process includes the sequence of reactors of the condensed carbonaceous material: a hydrogasification reactor; the stream and natural gas pyrolysis reactor; the methanol synthesis reactor and the recycling to the hydrogasification reactor of the hydrogen-rich gas stream remaining after the methanol synthesis and separation of the methanol product.
