摘要：
A catalytic upgrading process includes introducing a feed comprising crude oil to a steam cracking unit, thereby producing pyrolysis fuel oil (PFO). The PFO is introduced to a first catalytic depolyaromatization reactor to remove polyaromatics from the feed, thereby producing polyaromatics adsorbed to the catalyst and depolyaromatized PFO. The depolyaromatized PFO is introduced to a hydrocracking unit. The resulting benzene-toluene-xylenes (BTX) and liquid petroleum gas (LPG) are separated, and the BTX is introduced to a BTX complex to produce refined BTX. The LPG can then be introduced to the steam cracking unit. After depolyaromatization, a wash solvent is introduced into the first catalytic depolyaromatization reactor to remove the polyaromatics, regenerate the catalyst, and produce a mixture comprising the wash solvent and the polyaromatics. The wash solvent is separated from the polyaromatics.
