Abstract

The inventive method consists in carrying out rubber crumb thermolysis in a fluidized layer in the vertical flow of a supercritical hydrocarbon alkylaromatics-containing gas. The rubber crumb thermolysis is carried out in a reactor at a mass ratio between a solvent and residues less than 0.1. The solvent is also used in the form of a fluidizing agent, a heat carrier and for removing reaction products from the reactor, thereby enabling the solvent to flow in such a way that all the products produced by the rubber crumb thermolysis are totally removed from the reactor in the main stream with the solvent.

Description

technical field

[0001] The present invention relates to the chemical industry and to the recycling of rubber-containing industrial and domestic waste products such as used tires. Background technique

[0002] It is mainly produced by pyrolysis of rubber crumbs in supercritical hydrocarbon gas. After pyrolysis of rubber, carbon black is obtained (whose composition is close to that of carbon black used in rubber production), which has a high hydrocarbon content and has a small amount of hydrocarbon gas.

[0003] The disposal of rubber-containing waste products, mainly tires, is a very real modern problem. At the same time, products can be obtained as substitutes for derivatives of oil and gas feedstocks.

[0004] The obtained product can be used directly or after refining.

[0005] The following method is known: at pressures in the range of 1 to 6 MPa, at temperatures of 270 to 420° C. and at a solvent-waste ratio of 2-4:1, for recycling by thermal fluidization (pyrolysis) ...
