Process for purifying a liquid hydrocarbon fuel.

摘要

The invention relates to a process for purifying a liquid hydrocarbon product consisting of 5% by weight or less of high molecular weight contaminants having a molecular weight of at least 1000, wherein the product stream is contacted with a hydrophobic non-porous or nano-filtration membrane and the purified product stream is recovered as the permeate. Various liquid hydrocarbon products can be treated including process streams containing as the main product styrene, isoprene, butadiene, pentadiene, dicyclopentadiene, piperylene, C2-C5 mono-olefins or acrylates.
