PROCESS FOR THE CONVERSION OF PLASTIC WASTES

A process for the conversion of plastic wastes is described, involving the depolymerisation of the plastic material making up the waste. The plastic waste is extruded producing a molten mass which is mixed with hydrogen and fed to a hydrocracking reactor (25). According to the invention, the waste p...

Beschreibung
Zusammenfassung:	A process for the conversion of plastic wastes is described, involving the depolymerisation of the plastic material making up the waste. The plastic waste is extruded producing a molten mass which is mixed with hydrogen and fed to a hydrocracking reactor (25). According to the invention, the waste plastic, upon extrusion, is mixed with lubricants which cannot be regenerated, and the molten mass contains both plastic and lubricant wastes.The process can be carried out continuously, batchwise or semicontinuously.The product leaving the hydrocracking reactor (25) is distilled into a number of products.Also a plant for carrying out the process is described.
