METHOD AND DEVICE FOR PROCESSING POLYMER WASTES Russian patent published in 2020 - IPC C10B53/07 C10J3/02 C08J11/00 

FIELD: chemistry.

SUBSTANCE: invention relates to processing of heterogeneous polymer wastes by thermal decomposition, in particular to a method of processing polymer wastes and to a device for its implementation. Method is implemented by transfer of polymer component into gaseous phase with formation of nanoparticles of type {C_nH_m} and solid carbon-like phase formed by the rest molecules, including cross-linked systems with subsequent condensation of gas phase by microdroplet spraying of pre-cooled produced liquid product and separation of liquid and gas products, part of which is converted to heat energy and/or electric power providing the process. Part of the hydrocarbon gas product formed during condensation of the gas phase is heated, and heating of the polymer wastes is carried out by means of a preheated part of the hydrocarbon gas product formed during condensation of the gas phase.

EFFECT: technical result consists in stabilization of process and increase in yield and quality of valuable liquid hydrocarbon fractions, which increases efficiency of processing polymer wastes.
