Process for treating effluents originating from the preparation of hydrocarbon resins.

摘要

A process of hydrodechlorination of effluents originating from the preparation of hydrocarbon resins is described, the effluents consisting of about 90% of unconverted monomers and containing between 600 and 2500 ppm of organic chlorine. Said hydrodechlorination process comprises subjecting the said effluents to hydrogenation at a temperature of between 200 and 300 DEG C in the presence of a catalyst, preferably consisting of Ni-Mo supported on gamma -Al2O3.
