Upgrading a hydrocarbon feed and lowering its vapor pressure comprises contacting a pentene fraction with a higher olefin fraction in the presence of a dimerization/alkylation catalyst to produce gasoline and kerosene

摘要

Process for upgrading a hydrocarbon feed and lowering its vapor pressure comprises separating a C5 fraction (F1) including at least 2 wt.% pentenes, contacting F1 with a C6-C10 hydrocarbon fraction (F2) including at least 2 wt.% olefins in the presence of a dimerization/alkylation catalyst, and separating the effluent into a gasoline fraction boiling below 100 degrees C and a kerosene fraction boiling in the 100-300 degrees C range.
