摘要:
A hydrocarbon conversion process is described. The process includes contacting a hydrocarbon feed with an acidic catalyst under hydrocarbon conversion conditions in a hydrocarbon conversion zone. The hydrocarbon feed reacts to form a mixture comprising reaction products, the acidic catalyst, and deactivated acidic catalyst containing conjunct polymer. The mixture is separated into at least two streams, a first stream comprising the reaction products and a second stream comprising the deactivated acidic catalyst. The reaction products are recovered. The deactivated acidic catalyst is contacted with at least one silane or borane compound in a regeneration zone under regeneration conditions, the conjunct polymer reacting with the at least one silane or borane compound resulting in a catalyst phase and an organic phase containing the conjunct polymer and at least one silyl or boryl compound.

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.

We provide a process for regenerating a used acidic ionic liquid catalyst which has been deactivated by conjunct polymers in a reactor, by removing at least 57 wt % of the conjunct polymers originally present in the used acidic ionic liquid catalyst in a separate regeneration reactor, so as to increase the activity of the catalyst. We also provide a regenerated used acidic ionic liquid catalyst having increased activity.

We provide a process comprising: a. feeding a chlorinated-hydrocarbon and an ionic liquid catalyst to a treatment unit; b. operating the treatment unit at an elevated temperature to produce dechlorinated-hydrocarbon and HCl; and c. collecting the dechlorinated-hydrocarbon, wherein at least 90 wt % of the chlorides are removed. A second process comprises: a. creating an ionic liquid catalyst-rich zone in a distillation unit; b. passing chlorinated-hydrocarbon to the distillation unit; c. operating the unit under conditions causing removal of alkyl chloride to produce dechlorinated-hydrocarbon having a final boiling point close to a first final boiling point. A third process comprises: a. feeding alkylate gasoline blending component and ionic liquid catalyst to a treatment unit; b. operating the treatment unit; and c. collecting a dechlorinated-hydrocarbon, wherein at least 90 wt % of the chlorides have been removed and the dechlorinated-hydrocarbon has a second RON that is close to a first RON.
