First Claim
Patent Images
1. A process for hydrocarbon conversion, comprising:
- (a) providing a heavy oil hydrocarbon feed to a primary upgrading zone, wherein the primary upgrading zone comprises;
(1) at least one upgrading reactor; and
(2) at least one separator;
(b) obtaining a hydrocarbon stream comprising one or more C16-C45 hydrocarbons from at least one separator; and
(c) sending the hydrocarbon stream to an ionic liquid extractor containing a hydrocarbon feed-immiscible ionic liquid to remove metal compounds.

15. A process for removing metal compounds from a hydrocarbon feed produced by a primary upgrading process comprising:
-
(a) contacting the hydrocarbon feed comprising the metal compounds with a hydrocarbon feed-immiscible ionic liquid to produce a mixture comprising the hydrocarbon feed, and the hydrocarbon feed-immiscible ionic liquid; (b) separating the mixture to produce a hydrocarbon feed effluent and a hydrocarbon feed-immiscible ionic liquid effluent, the hydrocarbon feed-immiscible ionic liquid effluent comprising the metal compounds; (c) washing at least a portion of the hydrocarbon feed effluent with water to produce a washed hydrocarbon feed stream and a spent water stream; (d) contacting the hydrocarbon feed-immiscible ionic liquid effluent with a regeneration solvent and separating the hydrocarbon feed-immiscible ionic liquid effluent from the regeneration solvent to produce an extract stream comprising the metal compounds and a regenerated hydrocarbon feed-immiscible ionic liquid stream; and (e) drying at least a portion of at least one of the hydrocarbon feed-immiscible ionic liquid effluent;
the spent water stream, and the regenerated hydrocarbon feed-immiscible ionic liquid stream to produce a dried hydrocarbon feed-immiscible ionic liquid stream. - View Dependent Claims (16, 17, 18, 19, 20)
