摘要

Process for purifying a hydrocarbon-based feedstock, comprising one or more compounds to be eliminated, which comprises the steps: a) of extracting light compounds present within the feedstock; b) of filtering the compounds to be eliminated, in the presence of a supercritical fluid; c) of treating the feedstock using a conversion agent; d) of separating the purified hydrocarbon-based feedstock.
