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.

This application provides a process unit for the production of alkylate gasoline, comprising: a) a nozzle having an orifice that dispenses one or more recirculated streams comprising ionic liquid catalyst into a chamber in the nozzle, b) a conduit for introducing a hydrocarbon feed stream comprising an olefin to the orifice at a close distance from the orifice; and c) a throat connecting the chamber in the nozzle to an alkylation zone. The process unit can have multiple Venturi nozzles.
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.
