Abstract: The invention relates to a process for converting a feedstock comprising pyrolysis oil and a heavy hydrocarbon-based feedstock, with: a) a step of hydroconversion in a reactor; b) a step of separating the liquid effluent obtained from step a) into a naphtha fraction, a gas oil fraction, a vacuum gas oil fraction and an unconverted residue fraction; c) a step of hydrocracking of the vacuum gas oil fraction; d) a step of fractionating the hydrocracked liquid effluent obtained from step c) into a naphtha fraction, a gas oil fraction and a vacuum gas oil fraction; e) a step of steam cracking of a portion of the naphtha fraction obtained from step d); f) a step of fractionating at least a portion of the steam-cracked effluent obtained from step e); g) a step in which the pyrolysis oil fraction obtained from step f) is sent into step a).
