Regeneration of an acidic ionic liquid catalyst by addition of brønsted acids |
| 摘要 |
A method for regenerating deactivated acidic ionic liquid catalyst containing conjunct polymer is described. The method includes contacting the deactivated acidic ionic liquid catalyst containing the conjunct polymer with at least one Brønsted acid in a regeneration zone under regeneration conditions, resulting in a mixture comprising regenerated acidic ionic liquid catalyst, the Brønsted acid, the released conjunct polymer. The Brønsted acid is derived from a mineral acid and contains at least one organic group. The released conjunct polymer can be separated from the regenerated acidic ionic liquid catalyst and the at least one Brønsted acid. |

1. A method for regenerating deactivated acidic ionic liquid catalyst containing conjunct polymer comprising:
contacting the deactivated acidic ionic liquid catalyst containing the conjunct polymer with at least one Brønsted acid in a regeneration zone under regeneration conditions, the at least one Brønsted acid being derived from a mineral acid and containing at least one organic group, resulting in a mixture comprising regenerated acidic ionic liquid catalyst, the at least one Brønsted acid, and the released conjunct polymer; and separating the released conjunct polymer from the regenerated acidic ionic liquid catalyst and the at least one Brønsted acid. |
