RL-1润滑油加氢处理催化剂的开发与应用

DEVELOPMENT OF RL-1 LUBE OIL HYDROTREATING CATALYST AND ITS COMMERCIAL APPLICATION

介绍了RL-1润滑油加氢处理催化剂的性能与应用。RL－1催化剂以Ni－W为活性组分，具有良好的加氢-酸性裂解功能的平衡，对环烷基和中间基原油润滑油馆分的加氢考察表明，RL-1催化剂对多种不同性质的润滑油馆分在总压6．4MPa、空速0．5h－1、370～410℃条件下，可将该装置主要原料（减三线油）的粘度指数提高40，并生产出CC级柴油机油和YT－10橡胶填充油。

RL-1 catalyst used for lube oil hydrotreating with Ni-W as active constituents has well balanced hydrogenation and cracking activities. The study on hydrotreating both naphthalene and intermediate base lube oils indicates that at LHSV of 0. 5 h-1, overall pressure of 6. 4 MPa and 370-410℃ ,the viscosity index of hydrotreated lube stocks can be raised by 40 and greater. The catalyst regenerated after 2 years of commercial operation has an activity recovery rate of 95 %.
