SULFUR-CONTAMINATED IONIC LIQUID CATALYZED ALKLYATION

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; andb. 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.
