A method for pyrolysis of a mass of waste material, includes: providing a screw arrangement adapted to supply heat to the mass by mechanical shear; providing a reactor after the screw arrangement, adapted to supply heat to the mass in the absence of oxygen by heating the reactor wall; heating the mass to an exit temperature and increasing the pressure to an exit pressure in the screw arrangement; thermally degrading the mass in the reactor. The mass is brought into an extreme condition at the exit temperature and exit pressure by the screw arrangement, such that during the pressure drop pyrolysis occurs, thereby forming gaseous hydrocarbons within the connecting element.

The invention relates to a installation (4) for recycling composite materials comprising a horizontal reactor (5) with a first zone (1), second zone (2) and third zone (3), which are leak-tight and independent, aligned with and separated from one another by means of gates that allow the passage of the composite material to be recycled only when the process has ended in a previous zone. The first zone (1) comprises a rotation mechanism (9) for rotating the material and gas outlet means (8). The second zone (2) comprises air injectors (10) and gas outlet means (11). The third zone (3) comprises cooling means. The invention also relates to a method for recycling composite materials comprising a first pyrolysis phase, a second gassing phase for gassing the material resulting from the first phase, and a third cooling phase for cooling the reinforcement material.

[Solution] Provided is a method for producing a polyamide resin film, including: a step of producing a monomer from a raw material (A) for depolymerization, (2) a step of producing a polyamide resin (B) through polymerization using a raw material containing the monomer, (3) a step of refining the polyamide resin (B), and (4) a step of producing an unstretched film using a starting material containing the refined polyamide resin (B), and stretching the unstretched film.

The invention relates to a pyrolysis method and reactor for recovering at least one component from a carbon based material using thermal decomposition. The carbon based material is delivered to a pyrolytic chamber (1), exposed to a controlled atmosphere and heated to a decomposition temperature of the at least one component in the pyrolytic chamber (1) by microwave radiation. A variable power microwave radiation at frequencies between 300 MHz and 2200 MHZ is applied to sequentially increase a temperature in the pyrolytic chamber (1) over a temperature range including the decomposition temperature of the at least one component.

An embodiment provides a method for recycling tires, including: injecting, using a pump, a rubber material into a dissociating system, wherein the pump exerts a mechanical force upon the rubber material to reduce a size of the rubber material; within the dissociating system, creating a rubber material mixture, by: injecting a supercritical fluid to be mixed with the rubber material; heating, using a heat source, the rubber material mixture; and atomizing the rubber material mixture; and sending the resulting atomized rubber material mixture to a separating system to separate the rubber material mixture into different components.

Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The syngas quality, composition, and throughput are suitable for produce a wide range of chemicals.
