Abstract

The present invention relates to a plant (1) for the thermo-catalytic depolymerization of polyolefin plastic materials for the production of hydrocarbons comprising a reactor (10) inside which pyrolysis reactions of polyolefin plastic materials are intended to occur in the presence of a catalyst, with the consequent at least partial depolymerization thereof and the production of relatively low boiling hydrocarbons. The reactor (10) comprises at least one side wall (11), a bottom wall (12) and an upper wall (13) delimiting a reaction chamber (14), inside which the catalyst and polyolefin plastic materials are intended to be arranged. The reactor further comprises heating means (17) associated with at least one of the walls of said reactor and an internal mixer (18). The plant comprises at least one external recirculation chamber (20; 30) of the polyolefin plastic materials mixed with the catalyst contained in the reactor (10), said at least one external recirculation chamber (20; 30) being: arranged outside the reactor; fluidically connected to the reaction chamber of the reactor by means of an upper opening (21; 31) obtained near the upper wall (13) of the reactor and a lower opening (22; 32) obtained near the bottom wall (12) of the reactor; provided with an internal mixer (23; 33) configured to impart, in use, to the polyolefin plastic materials mixed with the catalyst an upward motion through said recirculation chamber (20; 30) from the lower opening (22; 32) to the upper opening (21; 31) so as to generate descending convective motions from the upper opening (21; 31) towards the lower opening (22; 32) in the reaction chamber; and provided with heating means (24; 34).
