Abstract

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).
