神府煤与胜利减压渣油共处理反应特性的研究

用共振搅拌反应器研究了神府煤与胜利减压渣油共处理液化的过程，在430 ℃、460 ℃、490 ℃；3 min～18 min，考察了煤的转化率。结果表明，煤油共处理的最佳反应温度为460 ℃，最佳反应时间为15 min，最高转化率为48.56％，反应过程可分为三个阶段：快速裂解加氢阶段、慢速裂解加氢阶段和缩聚反应阶段。采取了胜利减压渣油加氢处理、添加蒽油、煤油共处理三种措施所得苯可溶物作溶剂，结果表明，胜利减压渣油∶蒽＝1∶1作供氢溶剂时煤转化率有较大提高，达到54.11％；加氢处理后的胜利减压渣油供氢效果也不佳；用煤油共处理所得苯可溶物作供氢溶剂在460 ℃、 6 min时达最高转化率 65.33％。

Reaction characteristics of coprocessing of Shenfu coal and Shengli vacuum resid

The coprocessing of Shenfu coal and Shengli vacuum residue (SV) was studied using resonance agitation reactor. Coal conversion was investigated at 430 ℃, 46 ℃, 490 ℃, respectively, with reaction time from 3 min to 18 min. In this experiment system, the highest coal conversion of coprocessing is 48.56%; the optimum temperature and time are 460 ℃ and 15 min respectively. The reaction process can be divided into three stages, namely, rapid cracking hydrogenation, slow hydrogenation and polycondensation. Coal conversion is improved by adding anthracene into SVR, using hydrogenated SVR and benzene soluble fractions as solvent respectively. The hydrogenated SVR is not a good donor solvent for coal liquefaction. When benzene soluble fractions are used as solvent, the maximal coal conversion is 65.33% at 460 ℃ and 6 min.
