Treating a hydrocarbon feed comprises fractionating the feed, extracting resins from the heavy fraction, mixing the heavy fraction with the light fraction and passing the mixture to a cracking step

摘要

Treating a hydrocarbon feed comprising at least 80% of material boiling at 340[deg]C or more comprises fractionating the feed to obtain light and heavy fractions and a residue, where the heavy fraction comprises at least 90 wt.% of material boiling between 450 and 700[deg]C, passing the heavy fraction to an extraction step to remove resins, mixing the heavy fraction with the light fraction and passing the mixture to a cracking step.
