摘要
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; andb. 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.展开▼
