【Abstract】 This paper describes the development of coal indirect liquefaction which in cludes the syn-thesis of motor fuel from CO-H₂ and the synthesis of fuel alcohols from syngas.In the synthesis of motorfuel from CO-H₂ under reaction conditions of 260～280℃（ lst stage）and 320～350℃（2nd stage）,2.5MPa and 350～500h￣（-1） ,an excellent yield of motor fuel approximately 100g/m￣3（CO+H₂ ） can be ob-tained. In the synthesis of fuel alcohols from syngas under reaction conditions of 400～450℃,14～15MPa and 4000h￣（-1）, the alcohol product contained 74～77% of methanol and 12～15% of isobutanol,while the space time yield was 0. 21～0. 25 L alcohols/Lcat·h.6 refcrences are presented.更多还原
