Abstract
Predominantly aliphatic hydrocarbon materials may be obtained from carbonaceous solids by a sequence of steps comprising gasifying the carbonaceous solids, combining the gasification product stream with an internal recycle stream, separating certain impurities from the combined stream followed by cooling to liquefy and separate the hydrocarbon materials while directly reacting the remaining carbon monoxide and hydrogen in the presence of a catalyst to produce the internal recycle stream.
