PROCESS FOR CONVERTING A FEEDSTOCK CONTAINING PYROLYSIS OIL

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 o...

Beschreibung
Zusammenfassung:	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).
