| titleOfInvention | An integrated way to improve lubricant quality |
| abstract | (57) Abstract: A method is disclosed for hydrocracking a feedstock containing 50 or more straight run oils to adjust the hydrogen content, flash and / or distill to improve the quality. Residual oil is distilled under reduced pressure to adjust viscosity and volatility. The purified feed is subsequently dewaxed under high pressure with a medium pore size zeolite, such as HZSM-5 or a medium pore size molecular sieve. The dewaxed material is subsequently cascaded to a hydrofinishing step where, at a temperature in the range of 230 ° C. to 330 ° C. (450 ° F. to 575 ° F.), an effective aromatic having a metal hydrogenation action After contact with a compound-saturated catalyst and co-supplied hydrogen, after suitable flushing and distillation, it has a high viscosity index (VI), low aromatics content, low volatility, A lubricant product having excellent stability is formed. The hydrocracking, dewaxing and hydrofinishing steps can be multi-step. |
