The proposed method relates to the processing of carbon-containing raw material and may be used to obtain products containing amorphous silica and amorphous carbon of varying degrees of purity. The technical result consists in simplifying the production of a product containing amorphous silica and increasing the yield efficiency for such a product by decreasing the temperature to which the carbon-containing raw material is exposed. The method of producing a product containing amorphous silica and amorphous carbon includes the steps in which a carbon-containing raw material is dried at a temperature of 150-200° C. and the dried raw material is subjected to heat treatment at a temperature of 400-600° C., wherein the heat treatment is performed in the presence of an activator made of a readily fusible alloy. A device for carrying out the method is also proposed.

A pyrolysis system and method of use is capable of continuously processing feedstock. The pyrolysis system has enclosed pyrolysis tubes heated by a heating means to pyrolyze feedstock. Conveying mechanisms such as augers transport the feedstock into and through the pyrolysis tubes. The pyrolysis tubes can be heated to a desired temperature range using a heat exchanger, such as a molten metal bath, or inductively heated using induction coils wrapped around the pyrolysis tubes. The feedstock is physically separated from the outside environment by the enclosed pyrolysis tubes. A dynamic feedstock plug is formed upstream of the pyrolysis tubes to prevent air and moisture from entering via the inlet of the pyrolysis tubes. An outlet section connected to the outlets of the pyrolysis tubes separates the gaseous and solid products of pyrolysis and permits removal of the products while preventing air and moisture from entering into the system.

A continuous reflux reactor and controlled condenser system for thermochemical treatment of plastic and/or elastomeric waste has five zones with different complements. The zones comprises the bottom zone, pyrolysis zone, meeting zone, reflux zone and extraction zone. The reactor uses a reflux zone to increase the production of a light oil in the process. The reflux zone is equipped with some studded tubes that enhances the contact area. Cold molten salt is used as the cooling element of this step. The pyrolysis zone, where the material will be pyrolyzed, has the differential of being equipped with molten salt coils using hot molten salt as the heating element. After the material passes to all zones, the material goes to a cyclone that will condense heavier hydrocarbons present in this step and send the light hydrocarbons to the condensers.
