We provide a process for regenerating a spent acidic ionic liquid, comprising contacting the spent acidic ionic liquid with hydrogen and without an addition of a hydrogenation catalyst; wherein a conjunct polymer content is decreased in the spent acidic ionic liquid to produce regenerated acidic ionic liquid. We also provide a process for making an alkylate gasoline blending component, comprising: a) alkylating a mixture of isoparaffins and olefins using an acidic ionic liquid and an alkyl halide or a hydrogen halide, wherein a conjunct polymer accumulates in a spent acidic ionic liquid; and b) feeding the spent acidic ionic liquid and a hydrogen, and without an addition of a hydrogenation catalyst, to a regeneration reactor operated under selected hydrogenation conditions to produce a regenerated acidic ionic liquid that is used for the alkylating, wherein the conjunct polymer in the regenerated acidic ionic liquid is decreased by at least 50 wt %.

Apparatus for regeneration of acidic ionic liquid without addition of a hydrogenation catalyst

Disclosed herein are embodiments of a process which generally includes contacting i) a monomer or mixture of monomers, ii) a haloaluminate ionic liquid, and iii) one or more halide components in a reaction zone, and oligomerizing the monomer or mixture of monomers in the reaction zone to form an oligomer product. The combination of the haloaluminate ionic liquid and halide component can constitute a catalyst system which is used in embodiments of the process to produce the oligomer product.

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.

Regeneration of acidic ionic liquid without addition of a hydrogenation catalyst

A process and system for separating COfrom a flue gas stream is disclosed. The process involves (a) contacting a flue gas stream containing water vapor and COwith an ionic absorbent under absorption conditions to absorb at least a portion of the COfrom the flue gas stream and form a CO-absorbent complex; wherein the ionic absorbent comprises a cation and an anion comprising an amine moiety; and (b) recovering a gaseous product having a reduced COcontent.

Process for the separation of carbon dioxide from flue gas

An aqueous ionic absorbent solution is disclosed containing (a) about 15 wt. % to about 80 wt. % of one or more diluents, based on the total weight of the aqueous ionic absorbent solution; and (b) an ionic absorbent containing a cation and an anion comprising an amine moiety.

Disclosed herein is a method for improving the total energy demand required to separate carbon dioxide (CO) from an aqueous ionic absorbent solution in a post-combustion carbon capture process. The method involves (a) contacting a flue gas stream containing COwith an aqueous ionic absorbent solution under absorption conditions to absorb at least a portion of the COfrom the flue gas stream and form a CO-aqueous ionic absorbent solution stream, wherein the aqueous ionic absorbent solution comprises one or more diluents and an ionic absorbent containing a cation and an anion comprising an amine moiety; and (b) subjecting at least a portion of the CO-aqueous ionic absorbent solution stream to desorption conditions to form a CO-rich stream and an aqueous ionic absorbent solution stream having a reduced COcontent.

Process for reducing chloride in hydrocarbon products using an ionic liquid catalyst

Processes for the catalytic dechlorination of one or more hydrocarbon products involve contacting a mixture comprising the hydrocarbon product(s) and a carrier gas with a dechlorination catalyst under catalytic dechlorination conditions to provide a dechlorinated hydrocarbon product, HCl, and the carrier gas. The dechlorinated hydrocarbon product may be separated from the HCl and the carrier gas to provide liquid fuel or lubricating base oil.
