Beschreibung
Zusammenfassung:	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. On décrit un procédé de récupération de résidus de styrène sulfurés obtenus au cours de la purification de styrène produit par déshydrogénation catalytique d'éthylbenzène, qui consiste à mélanger lesdits résidus avec du gazole et à soumettre le mélange au craquage, à la distillation fractionnée et à l'hydrodésulfuration des fractions lourdes dont le point d'ébullition est d'au moins 140 °C.
