    摘要： We provide processes, and process units for practicing the processes, comprising a. regenerating a used catalyst comprising an ionic liquid catalyst and a chloride, from an alkylation reactor, in a hydrogenation reactor to produce a regenerated catalyst effluent; b. separating at least a portion of the regenerated catalyst effluent into a gas fraction comprising a hydrogen gas and into a light hydrocarbon fraction comprising a hydrogen chloride; c. recycling at least a part of the gas fraction comprising the hydrogen gas to the hydrogenation reactor; and d. recovering at least an amount of the light hydrocarbon fraction comprising the hydrogen chloride and recycling the at least the amount of the light hydrocarbon fraction to the alkylation reactor. The alkylation process units comprise a hydrogenation reactor, a fractionation unit, and connections for transmitting the gas fraction to the hydrogenation reactor and for transmitting the light hydrocarbon fraction to the alkylation reactor.

    摘要： A sulfur-contaminated ionic liquid catalyst is provided comprising 300 to 20,000 wppm of sulfur from a contaminant, wherein the catalyst is a chloroaluminate and it alkylates olefin and isoparaffin to make an alkylate gasoline blending component having a FBP below 221° C. A process is provided for making the alkylate gasoline blending component, comprising: a. feeding olefin feed comprising greater than 80 wppm of sulfur contaminant to a chloroaluminate ionic liquid catalyst, to make a sulfur-contaminated catalyst; and b. alkylating olefin feed with isoparaffin to make the alkylate gasoline blending component. A method to construct a refinery alkylation unit is provided comprising installing an ionic liquid alkylation reactor having an inlet that feeds a pure coker LPG olefin. An alkylation process exclusively utilizing coker LPG olefins is also provided.

    摘要： A regeneration process for re-activating an ionic liquid catalyst, which is useful in a variety of reactions, especially alkylation reactions, and which has been deactivated by conjunct polymers. The process includes a reaction step and a solvent extraction step. The process comprises (a) providing the ionic liquid catalyst, wherein at least a portion of the ionic liquid catalyst is bound to conjunct polymers; and (b) reacting the ionic liquid catalyst with aluminum metal to free the conjunct polymers from the ionic liquid catalyst in a stirred reactor or a fixed reactor. The conjunct polymer is then separated from the catalyst phase by solvent extraction in a stirred extraction or packed column.
