Patent ID: 8471086

Claim:
A process for producing hydrocarbon products, comprising: a) introducing a feed comprising an olefin, HCl, and an ionic liquid catalyst to a process unit; b) operating the process unit in a first mode; c) adjusting a molar ratio of olefin to HCl in the process unit; and d) after the adjusting step, operating the process unit in a second mode at a different molar ratio of olefin to HCl than that used in the first mode; wherein the first mode is different from the second mode, and the first mode and the second mode are selected from a distillate mode wherein greater than 50 wt % of a C 5 + product stream from the process unit boils at 700° F. (371 degree Celsius) or below and a lubricant mode wherein greater than 50 wt % of the C 5 + product stream from the process unit boils above 700° F. (371 degree Celsius); wherein increasing the molar ratio of olefin to HCl provides a higher amount of a lubricant; and wherein the molar ratio of olefin to HCl is greater than 140.
