Abstract (en)
[origin: WO9208773A1] Described is a process for recovering sulphurated styrene residues obtained in the purification of styrene produced by catalytic dehydrogenation of ethylbenzene, which comprises mixing said residues with a gasoil and subjecting the resulting mixture to cracking, fractionated distillation and hydrodesulphurization of the heavy fractions having a boiling point of at least 140 DEG C.
