Abstract: A process for producing renewable distillate-range hydrocarbons is provided. The process includes dehydrating a renewable C2-C6 alcohol feedstock to produce an olefin, oligomerizing the olefin the presence of a halometallate ionic liquid catalyst to produce an oligomer product and hydrogenating the oligomer product or fractions thereof to produce saturated distillate-range hydrocarbons.

Abstract: A process is provided for removing a heavy polynuclear aromatic (HPNA) compound from a hydrocarbon oil. The process includes contacting the hydrocarbon oil containing the HPNA compound with a lean hydrocarbon-immiscible liquid stream to produce a mixture comprising the hydrocarbon oil and a rich hydrocarbon-immiscible liquid containing the HPNA compound; and separating the mixture to produce a hydrocarbon oil effluent having a reduced level of the HPNA compound and a hydrocarbon-immiscible liquid effluent containing the HPNA compound. The hydrocarbon-immiscible liquid can be a halometallate ionic liquid, a liquid coordination complex, or a combination thereof.

Abstract: A process is provided for separating an ionic liquid from a liquid hydrocarbon, using an integrated coalescing system. The integrated coalescing system for separating ionic liquid from a liquid hydrocarbon may comprise: a. a bulk settler, that separates an emulsion comprising the dispersed ionic liquid with a wide range of droplet sizes into a clean ionic liquid phase and a separated liquid hydrocarbon phase comprising retained droplets; b. a pre-coalescer that receives the separated liquid hydrocarbon phase, separates out solid particles from the separated liquid hydrocarbon phase, and begins to form coalesced droplets of the retained droplets; and c. a coalescer that receives an effluent from the pre-coalescer, wherein the at least one coalescer comprises multiple layers of media having a fine pore size, and produces a clean hydrocarbon stream that is essentially free of the dispersed ionic liquid and additional amounts of the clean ionic liquid phase.

Abstract: Processes are provided for making an alkylate gasoline blending component, comprising: a. feeding an olefin feed comprising greater than 80 wppm of a sulfur contaminant comprising mercaptans, alkyl sulfides, and alkyl disulfides to a chloroaluminate ionic liquid catalyst, wherein a level of the sulfur contaminant accumulates in the chloroaluminate ionic liquid catalyst to make a sulfur-contaminated ionic liquid catalyst comprising 300 to 20,000 wppm of a sulfur; and b. alkylating the olefin feed with an isoparaffin using the sulfur-contaminated ionic liquid catalyst to make the alkylate gasoline blending component having a final boiling point below 221° C. An alkylation process exclusively utilizing coker LPG olefins is also provided.

Abstract: Disclosed are systems and methods which provide a process stream comprising a gaseous component, capture the gaseous component from the process stream by an ionic liquid solvent of a separator, and recover a captured gaseous component from the ionic liquid solvent in a regenerator. A second gaseous component from the process stream may be captured by the ionic liquid solvent of the separator, and the second gaseous component may be recovered from the ionic liquid solvent in the regenerator. Alternatively, the second gaseous component from the process stream may be uncaptured by the ionic liquid solvent, and the uncaptured second gaseous component may be recovered from a membrane unit.
