Tuning an oligomerizing step that uses an acidic ionic liquid catalyst to produce a base oil with selected properties |
| 摘要 |
We provide a process for making a base oil, comprising: feeding an olefin feed comprising a propylene to an oligomerization zone comprising an acidic ionic liquid catalyst prepared from an organic-based cation; and tuning an oligomerizing step in the oligomerization zone by mixing a C6+olefin with the propylene in the oligomerization zone to increase a viscosity index of the base oil. We also provide a process for making a base oil, comprising tuning an oligomerizing step by mixing a C6+olefin with a propylene in an oligomerization zone comprising an acidic ionic liquid catalyst prepared from an organic-based cation to increase a viscosity index of the base oil produced in the oligomerization zone; wherein the base oil has selected properties. |

1. A process for making a base oil, comprising:
a. feeding an olefin feed comprising a propylene to an oligomerization zone comprising an acidic ionic liquid catalyst prepared from an organic-based cation; and b. tuning an oligomerizing step in the oligomerization zone by mixing 20 to 28 wt % of one or more C6-C12 alpha olefin with the propylene in the oligomerization zone to increase a viscosity index of the base oil; wherein the viscosity index is from 50 to 90. |
