Hydrocarbon conversion process to remove carbon residue contaminants

摘要

The invention involves a process for hydrocarbon conversion. The process can include providing a feed to a primary upgrading zone and then treating the product from the primary upgrading zone with a feed-immiscible ionic liquid to remove carbon residue compounds.

主权项

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 carbon residue 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; andwherein at least 40 wt % of said carbon residue compounds are removed.
