METHOD OF REPROCESSING RUBBER WASTE.

摘要

The invention relates to the technology of reprocessing industrial and domestic waste. The problem addressed by the invention is that of reducing energy consumption and the quantity of toxic waste which enters the environment when rubber waste is reprocessed. This problem is solved by the use of superheated steam for the pyrolysis of the waste material. This method is novel in that superheated steam, amounting to between 18 and 110 per cent of the mass of the rubber waste, is used as the heat carrier, the gaseous products of pyrolysis are condensed together with the steam, and the condensate thus obtained is mixed with the solid residue which has first undergone preliminary grinding to produce particles of between 0.001 and 0.210 mm in size. The quantity of solid residue in the mixture is set at between 23 and 55.8 per cent of the total mass of the mixture. This process results in the production of a liquid fuel with improved environmental characteristics.
