Abstract. To produce liquid fuels from coal, either direct or indirect liquefaction routes can be used. The discussion of the former route is the subject of Chapter 6; the latter route will be discussed here. The indirect liquefaction route consists of the conversion of coal to synthesis gas (hydrogen plus carbon monoxide), and then the ...
