METHOD OF PRODUCING SOOT FROM RUBBER WASTES Russian patent published in 2013 - IPC C09C1/48 C08J11/00 C10B53/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of processing organic wastes and can be used in chemical and rubber industry. Rubber wastes are decomposed in a reactor. The decomposition products are divided into gaseous products and a carbon residue. The gaseous products are heated to 1200-1300 °C, oil is separated and sprayed to droplet size of 0.2-2.0 mm, mixed with the carbon residue ground to particle size of 0.1-1.0 mm in ratio of 1:(0.05-3.0) and subjected to thermal decomposition into soot and gases. The soot and gases are separated mechanically, and the soot is separated from the ash by electromagnetic separation. After separating oil, the gaseous products are burnt and the obtained heat energy is used for thermal decomposition of the mixture of oil and carbon residue. Gases from thermal decomposition of oil and carbon residue are burnt, and the obtained heat energy is used for thermal processing of gaseous products.

EFFECT: high quality of obtained soot, low power consumption of the process, improved environmental friendliness owing to reduced formation of toxic compounds.
