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; wherein the hydrocarbon feed-immiscible ionic liquid comprises at least one of trihexyl(tetradecyl)phosphonium chloride, trihexyl(tetradecyl)phosphonium bromide, tributyl(methyl)phosphonium bromide, tributyl(methyl)phosphonium chloride, tributyl(hexyl)phosphonium bromide, tributyl(hexyl)phosphonium chloride, tributyl(octyl)phosphonium bromide, tributyl(octyl)phosphonium chloride, tributyl(decyl)phosphonium bromide, tributyl(decyl)phosphonium chloride, tetrabutylphosphonium bromide, tetrabutylphosphonium chloride, triisobutyl(methyl)phosphonium tosylate, tributyl(methyl)phosphonium methylsulfate, tributyl(ethyl)phosphonium diethylphosphate, and tetrabutylphosphonium methanesulfonate; and wherein greater than 40 wt % of the metal compounds are removed from said hydrocarbon stream. |
