中文摘要：

利用小型滴流床反应器和NiW/Al203商业催化剂对全馏分龙口页岩油进行中压（≤9 MPa）加氢精制研究.考察反应温度、压力、液时空速和氢油比对加氢产物的硫含量、氮含量、密度、颜色和裂解程度的影响.结果表明：提高反应温度,降低液时空速,增大反应压力有利于加氢脱氮（HDN）反应进行;氢油比高于1 000之后,增加氢油比对加氢脱硫（HDS）和HDN影响较小;当反应温度为420℃、压力为7 MPa、液时空速为0.5 h-1、氢油比为1000时,页岩油的脱硫率和脱氮率达到最高,分别为99.6％和99.9％;龙口页岩油加氢精制的最佳反应温度为400 c℃、压力为9MPa、液时空速为0.5 h-1、氢油比为1000.

英文摘要：

The crude Longkou shale oil was hydrotreated in a bench-scale trickle-bed reactor with a commercial hydrotreating catalyst NiW/A102 O3 at medium hydrogen pressures （≤ 9 MPa）.The influences of pressure,temperature,liquid hourly space velocity （vLHs） and hydrogen-oil ratio on the sulfur content,nitrogen content,density,color and cracking degree of the product oils were investigated.The results show that decrease of vLHS and increase of temperature and pressure are beneficial for the hydrodenitrogenation （HDN） reaction.As the hydrogen-to-oil ratio exceeds 1 000 L/L,the effects of hydrogen pressure can be ignored.The highest degrees of hyrodesulfurization （HDS） and HDN,i.e.99.6％ and 99.9％ respectively,are achieved at the condition of 420 ℃,0.5 h-1,7 MPa,and 1000 L/L.The optimal conditions for the hydrotreating of crude Longkou shale oil are 400 ℃,0.5 h-1,9 MPa,and 1 000 L/L.
