Summary:Process for the treatment of a feedstock comprising a fraction of plastic and/or tyre and/or solid recovered fuel pyrolysis oil and a heavy fraction of hydrocarbons of fossil origin, said fraction of pyrolysis oil constituting less than 50% by weight of said feedstock, said process comprising: (a) a hydrodemetallization stage in a fixed bed reaction section comprising at least two permutable reactors which is fed at least by said feedstock and a gas stream comprising hydrogen, in the presence of a hydrodemetallization catalyst, (b) a hydrotreating stage in a reaction section comprising at least one fixed bed reactor, said section being fed by said effluent resulting from stage (a) and optionally a gas stream comprising hydrogen, in the presence of a hydrotreating catalyst, (c) a stage of separation of the effluent resulting from stage (b).
