石西混合原油减三线、减四线糠后油采用 RL—1加氢处理催化剂,在压力 6.0MPa,反应温度 360℃、370℃,空速0.5h~(-1),氢油比 1000:1的条件下,可将减三线粘度指数由83提高至 102;可将减四线油粘度指数由 77提高至 97.满足高粘度指数润滑油基础油标准要求。
The reaction temperature is 360 ℃, 370 ℃, the space velocity is 0.5h ~ (-1), the hydrogen-to-oil ratio is 1000: 1 under the conditions of the third-line viscosity index can be increased from 83 to 102; can reduce the four-line oil viscosity index from 77 to 97. Meet the high viscosity index base oil requirements of the lubricant.
