INTEGRATED ALKYLATION PROCESS TO MAKE BLENDED ALKYLATE GASOLINE

摘要

We provide an extracted conjunct polymer naphtha (45), comprising a hydrogenated conjunct polymer naphtha, from a used ionic liquid catalyst, having a final boiling point less than 246° C. (475° F.), a Bromine Number of 5 or less, and at least 30 wt % naphthenes. We also provide a blended alkylate gasoline (97) comprising the extracted conjunct polymer naphtha (45), and integrated alkylation processes to make the extracted conjunct polymer naphtha (45) and the blended alkylate gasoline (97). We also provide a method to analyze alkylate products, by determining an amount of methylcyclohexane in the alkylate products (80).

主权项

1. An integrated alkylation process, comprising:
a. regenerating a used ionic liquid catalyst comprising a conjunct polymer in a hydrogenation reactor (100) to make a regenerated catalyst effluent (10); b. mixing the regenerated catalyst effluent (10) or a separated liquid from the regenerated catalyst effluent (10) with an effluent from an alkylation reactor (40) to make a mixture; and c. separating out an ionic liquid catalyst stream (60) from the mixture made in step b) to produce a blended alkylate gasoline (97) comprising greater than 50 wppm methylcyclohexane.
