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).

Abstract: A method for determining corrosiveness of naphthenic acid in a crude oil feedstock is provided. The method includes the steps of providing a crude oil feedstock containing naphthenic acid; contacting the crude oil feedstock with iron for a period of time at a sufficient temperature for the iron to react with the naphthenic acid, forming iron salts. Under sufficiently high temperatures, at least a portion of the iron salts decompose to form ketone, which can be quantified. Measurements of the ketone can be used to correlate with the amount of iron lost from corrosion given a certain level of naphthenic acid present, giving a measure of the corrosivity of crude oil feedstock.
