摘要
采用管式液相加氢技术,设计在5 L催化剂装量的工业侧线装置上,以HDO-18为催化剂,开展重整生成油脱烯烃可行性研究,并考察了反应空速、氢油比、反应温度、反应压力等适宜操作条件。长周期运行结果表明:该技术可以使加氢后重整生成油溴指数<100 mg Br/100 g油,产品中的芳烃损失<0.5%,可替代白土吸附或常规后加氢工艺脱除重整生成油的烯烃。其最佳操作条件为:反应温度170℃、反应压力1.5 MPa、体积空速12 h-1和氢油比4:1。
The feasibility study of reformate hydrodeolefin was carried out,and suitable operating conditions were investigated,in the industrial side line device,by using tubular liquid phase hydrogenation process with HDO-18 as catalyst.The test results proved that Bromine index of hydrogenated reformate was lower than 100 mgBr/100 g oil,the loss of aromatics was lower than 0.5%,and the tubular liquid phase hydrogenation technology could replace clay adsorption or conventional post-hydrogenation process.The best operating conditions were determined as follows:the reaction temperature 170℃,the pressure 1.5 MPa,the space velocity 1.2 h-1 and H2/Oil ratio 4.
