Abstract: The nature of the method of treating multicomponent, composite and combined materials, consisting of organic and inorganic, non-metallic and metallic components and especially of waste from electronic and electric devices and equipments, consists in that the treated materials are pretreated by removing contaminating components containing toxic heavy metals and poly-chlorinated biphenyls, by grinding the waste to particles having the size of 5 to 25 mm at most, and they are subjected, in an inert or reducing environment at a temperature of 350° C. to 600° C. and at a pressure of 100 kPa to 10 MPa, to the action of blades of a rotational mechanism for 10 seconds to 10 minutes, and to the action of a moving bed of solid particles of a substance, performing whirling motion.

Abstract: The nature of the process consists in that the low-grade organic substances are subject, at a temperature of 150.degree. C. to 700.degree. C. and at a pressure of 0.1 MPa to 2.5 MPa, to the action of a moving bed of solid particles of a substance which perform whirling motion, whereby the solid particles of a substance constituting the moving bed are set to whirling motion by intensive agitation.The device consists of a reaction chamber (1) with a rotation mechanism (2) which rotation mechanism (2), located rotably in the faces of the reaction chamber (1), consists of a shaft (3) to which vanes (5) are symetrically attached by means of driving discs (4). The vanes (5) may be arranged in 3 to 10 rows, and they may be provided with openings (5.1) or cut-outs (5.2) of various geometrical shapes, and they may be divided into individual segments (5.3). Also the driving discs (4) may be provided with openings (4.1) of various geometrical shapes.
