PROCESS AND INSTALLATION FOR PYROLYSIS OF A PRODUCT IN THE FORM OF DIVIDED SOLIDS, IN PARTICULAR POLYMER WASTE

摘要

An installation for pyrolyzing divided solids, such as waste plastics, rubbers, or elastomers. The installation has a device for making divided solids suitable for facilitating pyrolysis by a pyrolysis reactor. The reactor inlet is leak-tightly connected to the preconditioning device and has at least one heating transfer member for transferring the divided solids within the reactor while also pyrolyzing the solids. The member is a conveyor screw or a vibrating tube, and being made of a material that is associated with means for heating it by the Joule effect. The preconditioning device includes liquefaction means for bringing the substance to the outlet of the preconditioning device in a liquid state at an outlet temperature, and a regulator for regulating the temperature of the substance at the outlet from the preconditioning device as a function of a temperature representative of an inlet temperature of the reactor.
