Abstract
Process for the purification of a hydrocarbon stream including: a) Providing a hydrocarbon stream having a diene value of at most 1.5 g I2/100 g and a bromine number of at least 5 g Br2/100 g, and containing at least 10 wt % of pyrolysis plastic oil; d) contacting the effluent obtained in step a) with silica gel, clays, alkaline or alkaline earth metal oxide, iron oxide, ion exchange resins, active carbon, active aluminum oxide, molecular sieves, alkaline oxide 10 and/or porous supports and silica gel, or any mixture thereof; e) performing a second hydrotreating step; and f) recovering a purified hydrocarbon stream, where the second hydrotreating step is performed over at least one catalyst that presents both (i) an hydrotreating function and (ii) a trap function.
