    摘要: Systems and methods for recycling waste plastic can convert the waste plastic into a form of purified crude oil that includes one or more organic molecular species and that is free, or substantially free, of impurities such as acids and metals. In some systems and methods, the plastic is heated under vacuum conditions to effect depolymerization of the plastic, which yields a vapor, and the vapor is then directly contacted with a pH adjusted solution in a vapor treatment system. In some systems and methods, a continuous batch process is employed.

    摘要: A method and apparatus for pyrolytic destruction of polymer products including whole vehicle vulcanised rubber tyres is disclosed. The apparatus 111 has a reaction chamber 153 into which a tyre can be placed, and immersed for pyrolytic decomposition in a molten alloy of zinc with a minor proportion of aluminium. The apparatus 111 has a heated reservoir 155 in which the alloy is maintained in a molten state, and from where it can be transferred to the reaction chamber 153 to immerse the tyre. Fluid hydrocarbon byproducts are drawn off for condensation and recovery, and solid zinc sulphides are also recovered. Where steel belted tyres are processed, carbon and steel residues are also recovered.

    摘要: 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. In this way there occurs depolymerization, cracking and state transformation of macromolecular, solid and liquid organic fractions and their separation from the composite material in the form of organic vapours and gases, and disintegration of inorganic non-metallic fractions to small particles and increase of metal concentration in the inorganic phase.
