最近 ,我国科学家在“煤练油”技术方面取得了重要成果 ,在催化剂的作用下 ,从 5吨煤炭中合成出 1吨成品油。从而使我国成为世界上为数不多的掌握“煤练油”技术的国家之一。1 “煤练油”技术概况“煤练油”被称为“煤基液体燃料合成技术” ,该技术工艺通过直接液化及间接液化 Recently, our scientists have made important achievements in the technology of “coal training oil” and have synthesized 1 ton of refined oil from 5 tons of coal under the action of catalysts. Thus making our country one of the few countries in the world to master the technology of “coal and oil drilling”. 1 “coal training oil” Technical Overview “Coal training oil” is known as “coal-based liquid fuel synthesis technology”, the technology process by direct liquefaction and indirect liquefaction
