Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for reducing chloride in a hydrocarbon, comprising: a. feeding a chlorinated-hydrocarbon, comprising greater than 50 up to 5,000 ppmw chlorides, and an ionic liquid catalyst comprising an anhydrous metal halide to a treatment unit; wherein an amount of the ionic liquid catalyst comprising the anhydrous metal halide in the treatment unit is from 20 ppmw to 2 wt %; b. operating the treatment unit under conditions including a temperature from 65.6°…
