摘要
采用PHI-01异构脱蜡催化剂对中间基减三线馏分油(VGO 3馏分油)和中间基减三线苯酚精制油(VGO 3精制油)进行加氢精制—异构脱蜡—补充精制三段加氢工艺实验。结果表明:以VGO 3馏分油为原料,在加氢精制段氢分压为15.1 MPa,反应温度为390℃,体积空速为0.46 h~(-1),氢油体积比为1 000∶1,异构脱蜡段氢分压为15.1 MPa,反应温度为365℃,体积空速为1.0 h~(-1),氢油体积比为500∶1的条件下,制得Ⅲ类基础油(VHVI 6)的收率为33.22%;以VGO 3精制油为原料,在加氢精制段氢分压为15.1 MPa,反应温度为385℃,体积空速为0.46 h~(-1),氢油体积比为1 000∶1,异构脱蜡段氢分压为15.1 MPa,反应温度为360℃,体积空速为1.0 h~(-1),氢油体积比为500∶1的条件下,制得Ⅲ类基础油(VHVI 5)的收率为42.21%。以VGO 3馏分油为原料,经过苯酚精制—加氢精制—异构脱蜡—补充精制四段工艺处理后获得的Ⅲ类基础油收率仍较直接采用三段加氢处理的高出近9个百分点。
The PHI-01 isomeric dewaxing catalyst developed by Petrochemical Research Institute,PetroChina,was used to carry out hydrorefining-isomeric dewaxing-hydrofinishing the three-stage hydrogenation test hydrofining on the intermediate vacuum cut 3 distillate oil(VGO 3 distillate oil)and intermediate vacuum cut 3 phenol refined oil(VGO 3 refined oil).The results showed that with VGO 3 distillate oil as raw material,under the conditions of the hydrogen partial pressure 15.1 MPa,reaction temperature 390℃,volume space velocity0.46 h~(-1),volume ratio of hydrogen to oil 1 000∶1in the hydrofining section,hydrogen partial pressure15.1 MPa,reaction temperature 365℃,volume space velocity 1.0 h~(-1),volume ratio of hydrogen to oil 500∶1 in the isomerization dewaxing section,the yield of VHVI 6Ⅲbase oil was 33.22%after the treatment of three sections;with VGO 3 refined oil as raw material,under the conditions of hydrogen partial pressure 15.1 MPa,reaction temperature385℃,volume space velocity 0.46 h~(-1),hydrogen to oil 1 000∶1 in the hydrofining section,hydrogen partial pressure 15.1 MPa,reaction temperature360℃,volume space velocity 1.0 h~(-1),hydrogen to oil 500∶1 in the isomerization dewaxing,the yield of VHVI 5Ⅲclass base oil was 42.21%after the treatment of three sections.With VGO 3 distillate oil as raw material,the yield ofⅢclass base oil obtained by phenol refining-hydrofining-isomerization dewaxing–hydrofinishing was still higher than that of directly using the three sections of hydrotreating nearly 9 percentage points.
