Abstract
The effective coupling and combination of coal gasification and coal liquefaction techniques to produce ultra clean liquid fuels from carbonaceous matter preferably provided from an abundance of waste coal mining material. The method and apparatus includes a final sulfur washing step utilizing a zinc oxide membrane to remove virtually all sulfur from synthetic gas produced in an entrained flow gasifier before the synthetic gas is permitted to enter a slurry phase vessel having a catalyst used to produce a parafin from which liquid fuel is produced. The liquid fuel is preferably an ultra clean, high cetane, sulfur-free diesel fuel.
