The equipment consists of a reactor, which heats up the worn tires, other polymer waste material and the solvent up to 300 °C, which results in a pressure increase inside of the reactor up to 300 °C; of a refrigerating unit, which carries out the distillation of the liquid products, a nitrogen station for a neutral environment, a heat exchanger for warming up the solvent up to 100 °C, a ventilation equipment, a rinsing container for a separation of the technological carbon from the steel cord, tanks for the solvent, the liquid products of distillation and the rinsing liquid.

Description

METHOD AND INSTALLATION FOR PRODUCTION OF TECHNOLOGICAL
CARBON AND MOTOR FUEL DURING A PROCESSING OF WORN TIRES
AND OTHER POLYMER WASTE MATERIALS
The invention regards a physical and chemical processing of worn tires and of other polymer wastes in order to produce technological carbon and motor fuel, which are used in many industrial branches, for instance for a production of asphalt, of anode mass for arc furnaces, for electrolisers, etc.
At present, the problem of processing worn tires and other polymer wastes is very urgent due to a continuous increase of amounts of those wastes. The method described herein allows for an efficient processing of those wastes and for a production of valuable products. First of all the technological carbon, which is now produced using large amounts of crude oil and gas.
The method allows for a solution of the ecological problem as well as for a wider production base of the hydrocarbon raw materials.
The known method of processing the waste materials in a hydrocarbon solvent consisting of one or more alkylobenzols at temperature of 270 - 420 °C and under a pressure of 1 - 6 Mpa with a presence of rare-earth metals (RU2110535 Cl 10.05.98).
The shortcoming is the presence of rare-earth metals, which makes the process more expensive, and an elimination of rare-earth metals from the technological carbon is very complicated.
Another method is known, analogous to that previously mentioned, (RU 2167168 C1 20.05.2001 ), which does not contain any rare-earth metals, and after the distillation of the liquid fraction at the boiling temperature of 210 °C, the worn waste materials are introduced again during the liquefaction as a supplementary component of the solvent. A high degree of complication is a shortcoming, a low pressure. The most similar is the method (patent application number 95/0007, C 08 I
11/20, 1995 year), where hydrocarbon wastes from the synthetic rubber production with an addition of rare-earth metals are used.
The shortcoming is the presence of rare-earth metals, which are difficult to remove.
All the methods mentioned above are concentrated on the liquid products of the utilisation, which is not the most important, as technological carbon is the most valuable product.
The presented problem was solved with a method, which uses the liquefaction of worn tires and of other polymer materials in the environment consisting of a hydrocarbon solvent, which is a mixture of a worn motor oil and of liquid waste materials, which are created during the production of synthetic rubber at 1- 20:10 ratio at temperature of 300 °C under pressure of 12 Mpa. The pressure is created independently. The solvent is an efficient donor of hydrogen in sufficient quantities. The method is technologically simple and economically convenient, as waste materials are the only ones used in the process. This method allows for a recovery of up to 30% of the technological carbon compared to the mass of worn tires, and up to 50% of entire mass gets liquified. The waste materials/solvent mass ratio = 1 :1.
The method is carried out as follows.
The cage 20 containing worn tires is put into the reactor 1 , then the cover 3 is closed, valves 20, 21 are opened to purge the reactor with nitrogen from the nitrogen station. Afterwards, valves 20, 21 are closed. Valves 18,19 are opened, and the solvent from the tank 15 is poured into the reactor, so that 1/8 of the reactor is empty, but the waste materials are covered. The solvent composition is 20:1. The waste materials/solvent ratio = 1 :1. The solvent flows through the heater 7 and get heated up to temperature of 100 - 120 °C by means of the heat exchanger 5. Valves 18, 19 are now closed. By means of the heat exchanger 4, the reactor is heated up to 300 °C. The pressure increases up to 12 Mpa during the heating. Now the pressure is lowered down to 7 Mpa.
Valve 21 is opened for that purpose. The liquid products are distilled while flowing through the cooler 18 and gather in the container 16. The valve 21 is now closed. The procedure is repeated several times until the pressure is stabilised at pressure of 7 Mpa. The heat exchanger 4 is switched off at temperature of 300 °C. After the pressure has stabilised, the valve 21 is opened which decreases the pressure down to 1 atmosphere. The valve 21 is now closed, and valve 20 is opened, which puts nitrogen under pressure into the reactor. Now the valve 20 is closed, and the valve 22 is opened, which pushes out the liquid products and decreases the pressure down to the atmospheric one. Now the valves 23, 24 are opened, the cover 3 is closed, the fan 9 is switched on to purge the reactor with air. The air from reactor is purified while flowing through the decontamination device 10.
Now the cage 2 is put out from the reactor and replaced with another. The cover 3 is closed. The cage 2 is put into the rinsing device 11 , the cover 12 is closed.
The valve 27 is opened and fills the rinsing device with the rinsing liquid from the container 17. The valve 27 is closed, the valves 25, 26 are opened, the pump 13 is started, which presses the liquid through the ceramic filter 14 removing the technological carbon from the liquid. The examples of the realisation of the method proposed herein are presented in the table.
The technological equipment consists of the reactor of 2.6 cu. m. volume. Worn tires of mass of 300 kgs are loaded into the reactor. The hot solvent (consisting of liquid waste material from the synthetic rubber production and of worn motor oil in the ratio of 20:1 ) is poured into the reactor. The solvent mass is 300 kgs, its temperature is 100-120 °C. The full reactor is heated up to 300 °C. The pressure is decreased from 12 MPa down to the 7 MPa during the reactor heating up. While the pressure is getting lowered, the liquid products flow to the cooler, are getting distilled there and then gathered in the container. The pressure decrease from 12 MPa down to 7 MPa is repeated several times until the pressure is stabilised at 7 MPa. After the pressure has stabilised at 7 MPa, the valve is opened, which results in the pressure decrease down to 1 Mpa. Nitrogen is let into the reactor to remove the remainders of the liquid fractions. The cover is opened, the reactor purged with air, the cage is replaced with another cage, which contains waste tires. The cage is rinsed with a liquid. The rinsing liquid flows through the ceramic filter and is purified of technological carbon.
Operations are then repeated ace. to the description presented above.
Example 1.
Processing of waste rubber for the synthetic rubber production waste/worn motor oil ratio = 20:1.
Example 2. For ratio = 10:1.
Example 3.
For ratio 20:1. Polymer wastes only, no rubber products.
All the examples: solvent/waste materials ratio = 1 :1 .
