摘　　要：通过高压釜研究了山东某炼厂的催化裂化油浆(FCC油浆)与新疆哈密地区煤共处理效果.结果表明:当煤粉添加量为30%时,油煤浆的黏度已经达到了1 375mPa·s,远大于煤直接液化中油煤浆的黏度,不利于泵的输送,因此,如何降低油煤浆黏度是煤油共炼技术要解决的重要问题之一;在煤粉添加量为30%~35%、反应温度为450℃、停留时间为2.0h的条件下,FCC油浆与煤共处理的反应效果较好,转化率超过了98%,油产率基本维持在80%;对FCC油浆进行加氢预处理来改善其性质,可显著降低油煤浆的黏度,同时提高了煤粉添加量为40%条件下的煤油共处理效果,使转化率由92.4%上升至96.5%,油产率由71.12%上升至79.19%.The reaction effect of FCC slurry from a Shandong refining factory and coals from Hami was studied.The results show that when the coal addition reaches 30%,the viscosity of oil-slurry is 1 375 mPa·s,which is much higher than that of oil-slurry produced by directlyliquefied coals,and this is not good for pump transfer.Therefore,how to reduce the viscosity of oil-slurry is one of the important problems that the coal-oil synergistic technology has to solve.When the coal addition is 30%-35%,the reaction temperature is 450℃ and the residence time is 2.0h,better co-processing effects of FCC slurry and coal reactions can be achieved with the conversion of 98% and oil yield of 80%.With hydrogenation of FCC slurry to improve its quality,the viscosity of oil-slurry can be reduced considerably,and the effects of co-processing can also be ameliorated when the coal addition is 40%.Furthermore,the conversion rises from 92.4% to 96.5%,and the oil yield increases from 71.12% to 79.19%.
