Abstract
Predominantly aliphatic lower hydrocarbon materials may be obtained from carbonaceous solids by a sequence of steps comprising gasifying the carbonaceous solids, combining the gasification product stream with first and second internal recycle streams, separating certain impurities from the combined stream followed by cooling to liquefy and separate the hydrocarbon materials, directly reacting the remaining carbon monoxide and hydrogen in the presence of a catalyst to produce a first internal recycle stream, fractionating the separated hydrocarbon materials to separate and recover the predominantly aliphatic lower hydrocarbon materials from the higher hydrocarbon materials, subjecting the higher hydrocarbon materials to steam cracking to produce a second internal recycle stream, and recycling the internal recycle streams for combination with the gasification product stream as noted above.
