This invention has as its object a method for selective hydrogenation of a feedstock comprising a pyrolysis gasoline carried out in a three-phase reactor.

Method for the selective hydrogenation of a pyrolysis gasoline feedstock with a three-phase reactor

A subject-matter of the invention is a process for the depolymerization of a polyester feedstock comprising opaque PET, the said process comprising at least the stages of conditioning, of depolymerization and of separation of the diol and of separation of the liquid effluent rich in monomers, followed by a decolouration stage.
