摘　　要：以中/低温煤焦油460℃以下馏分为原料,在30mL小试加氢反应装置上对其进行加氢改质,制备清洁燃料油.加氢反应过程中系统压力为8MPa～15MPa,反应温度为400℃～460℃,氢/油体积比为1800～2000,煤焦油原料全部转化,产品油平均体积收率大于106%,进一步分离后获得汽油馏分(≤170℃)和柴油馏分(>170℃),其中汽油馏分和柴油馏分分别占总体积的22.75%和77.25%(该比例随不同煤焦油来源而不同),无任何尾油残留,且均达到国家标准中93#汽油和0#柴油规定的各项技术指标;此外,煤焦油和产品中硫含量的分析结果表明,产品油中硫的含量大大降低,完全可以达到清洁燃料油的标准.Clean fuel was prepared from the middle/low-temperature coal tar via hydrocatalysis route on a 30 mL hydrogenation reactor under the effect of series of catalysts. The pressure and temperature as well as H2/oil ratio were set as 8 MPa-15 MPa, 400℃-460℃, 1 800-2 000 respectively during the reaction. All of the coal tar was converted and the volume receive of clean oil product was higher than 106 %. And then the product oil was separated as gasoline and diesel with the ratio as 22.75% and 77.25% respectively （the ratio is changeable with the different raw coal tar）. There was no residual oil left during the hydrogenation process. The obtained gasoline and diesel was up to the grade of national standard. In addition, the analysis result of the sulfur content was greatly decreased compared to the raw material during the conversion process which could be used as clean fuel.
