    The invention relates to a method and device for producing hydrocarbons from coal and can be used in the refining and coal chemical industries. A method of producing hydrocarbons from coal is known, in which dry coal particles 40-50 µm in size are injected into a chamber, where coal is treated with hot hydrogen at 10-50 mS at a temperature in the chamber equal to Y. It is also known a device for producing hydrocarbons from coal, including hydrogenation chamber with coal injection system 1. . The disadvantages of the known method and device are the complexity of the process and the unreliable operation of the device. The closest to the present invention is a method for producing hydrocarbons from coal, comprising the steps of combining dry powdered or lump coal supplied by means of a sealed charging device, in a preparatory chamber with friction elements, heating and catalytic hydrogenation in the presence of hydrogen with increased output, followed by separation into mountains than the state of the products obtained and. . The closest to the present invention is a plant for producing hydrocarbons from coal, including a feed hopper, a preparatory chamber with friction elements mounted on the shaft, and a hydrogenation chamber with hydrogen supply nozzles connected to a pressure source I . The disadvantages of these methods and set-ups are the complexity of the technology for producing hydrocarbons and the installation, since the process is carried out in four extruders operating in series with valves that operate with a stepwise increase in pressure. The purpose of the invention is to simplify the process and installation technology. The goal is achieved in that according to the method of producing hydrocarbons from coal, which includes the steps of compressing dry powdered or lump coal supplied by a fused charging device, in a preparatory chamber with friction elements, heating and catalytic hydrogenation in the presence of hydrogen at elevated pressure followed by separation in the hot state of the products obtained, the compression and heating stages of the coal are carried out in the preparatory chamber The plastic state due to the heat of friction of coal with friction elements and hydrogen is carried out at 400-535 ° C, pressure of 356-530 atm and heavy traffic, resulting in the distribution and breakdown of plastic coal obtained at the stage of compression and heating, with simultaneous feeding hydrogen. In a device for carrying out a method for producing hydrocarbons from coal, including a feed funnel, a preparatory chamber with friction elements mounted on a shaft and a hydrogenation chamber with nozzles for hydrogen supply connected to a pressure source, the preparatory chamber is connected directly to the hydrogenation chamber, and with it in the same housing, the hydrogenation chamber is equipped with a rotor with blades located along its axis, a shut-off valve located at its outlet end, and a heat exchange pipe In addition, hydrogen supply nozzles are equipped with check valves and are located radially and axially between the rotor blades. The rotor blades are interrupted and arranged in a spiral. The hydrogenation chamber has an internal diameter twice that of the preparatory chamber. The preparatory chamber and the hydrogenation chamber have the same diameter and. the diameter of the rotor shaft is half the diameter of the shaft of the friction elements. The shaft of the friction elements and the rotor have individual drives. The distance I; by the partition walls of the friction elements and their angle of inclination to the vertical line are made decreasing in the direction towards the hydrogenation chamber. Horizontal or spiral-shaped grooves are made on the inner wall of the preparatory X1mer from the side, opposite to the position of the hydrogenation chamber. The amount of friction heat introduced into the coal depends on the ms of the drive, which, through rotating friction elements, introduces coal into the mass. The faster the shaft with friction elements rotates, the faster the coal particles are transferred to the plastic state and transported to the hydrogenation chamber. At the same time, with the increasing number of revolutions associated with the shaft of the rotor frictional elements, intensive mixing and swirling of the coal with the supplied hydrogen occurs in the hydrogenation chamber, due to which the hydrogenation process proceeds quickly and evenly throughout the hydrogenation chamber. This results in high plant capacity and, therefore, the most economical process for hydrogenation. The pressure required for hydrogenation is created at the beginning of the preparation chamber, whereas the main heating is performed at the end of the preparation chamber. FIG. 1 shows the proposed installation, the general view; in fig. 2 a preparatory chamber and a hydrogenation chamber, having a different inner diameter, a longitudinal section; in fig. 3 — hydrogen supply nozzles, longitudinal section; in fig. 4 is a section A-A in FIG. 2; in fig. 5 is a preparatory chamber, the longitudinal section of FIG. b - installation with a vertical hydrogenation chamber; Objections are seen in FIG. 7, a preparatory chamber and a hydrogenation chamber having the same internal diameter, a longitudinal section. The installation includes a feed hopper 1, a preparatory chamber 2 with friction elements 3 mounted on shaft 4, and a hydrogenation chamber 5 with nozzles 6 for supplying hydrogen connected to a pressure source 7. The hydrogenation chamber 5 is equipped with a rotor 8 with blades 9, a locking valve 10 located at its outlet end, with a heat-jacket 11. The nozzles 6 for supplying hydrogen to the hydrogenation chamber 5 are equipped with non-return valves 12 and are located radially and axially between the rotor blades 9 of the rotor 8 (FIG. 3). The horizontal or spiral grooves 13 and 14, respectively, are made on the inner wall of the preparatory chamber 2 from the side opposite to the chamber of hydrogenation 5. The shaft and the rotor 8 can be driven in rotation from an individual drive 15. The installation for carrying out the proposed method works as follows. Powdered or lump coal is loaded into the feed hopper 1. With the 8 charging hopper 1, the valve 16 is closed and pressure is generated. Then the coal in the form of powder or pieces with the aid of the cell sector shutter 17 is fed into the preparation chamber 2. It is necessary that the lumpy or powdered coal does not form any bridges in the hopper 1 and thus does not cause interference in operation. For this purpose, mixing elements are located in the feed hopper 1, which allow constant movement of the coal in the feeding hopper. In order to allow continuous operation, a second feed funnel 1 can be provided, the valve of which and the supply to the preparation chamber 2 are switched if the first tank is empty. Cellular sector shutter 17 allows to carry out a metered supply of coal into the suction chamber. At the same time, the cell sector stopper 17 ensures the tightness of preparatory chamber 2. In preparatory chamber 2, which is divided into two zones, namely the pressure generating zone 18 and the friction zone 19, the coal is moved by the rotating shaft 4 with the friction elements 3 in the direction towards the hydrogenation chamber 5. Due to the fact that the distance between the partitions of the friction elements 3 and the angle of their shaklon to the vertical are made smaller in the direction of the scientific research institute to the hydrogenation chamber 5, the material undergoes constant compression. Due to the rotational movement of the shaft 4 with friction elements, the pieces of coal are transported in the direction of the hydrogenation chamber 5. Parts of the coal undergo a shearing movement, thereby creating frictional heat and the coal particles agglomerate to an increasing extent. In a similar way, the coal particles from its lumpy or powdered state transform into the agglomerate state and from it again due to the increasing shear load. into a plastic state. In order to speed up the hydrogenation process, at the end of the preparation chamber 2, hydrogen can be supplied to the coal that has become plastic, which has a temperature of 400 ° C and a pressure of 400. bar. Hydrogen is fed through nozzles 6 connected by a pipe 20 to a source 7 of pressure (a compressor) and a source 21 of hydrogen. Brought to the preparatory chamber to a high temperature plastic and already. Hydrogen-enriched coal gets due to the transporting movement of the friction elements .3 hydrogenation chamber 5, in which it, thanks to the blade 9 of the rotor 8 and the static mixing nozzle 6 located between them, exposes with an intensive mixing and shearing action. Hydrogen blown by compressor 7 to the process pressure is simultaneously blown through all the mixing nozzles 6 into the hydrogenation chamber 5. Due to the fact that the mixing nozzles 6 are located in the hydrogenation chamber 5 radially and axially, hydrogen is blown into many places at the same time and almost in the center, due to which intensive uniform mixing and grinding of the plastic coal is achieved in the entire volume of the hydrogenation chamber 5. The consequence is extremely intense and rapid hydrogenation. By grinding, the splitting of the agglomerated particles of coal and thereby the hydrogenation process is significantly accelerated. Breakdown or scraping of the contents of the chamber 5 hydrogenation occurs primarily on the inner wall of the chamber. Since the hydrogenation chamber 5 is also encompassed by the heat transfer jacket 11 passing in the radiographic or axial direction, additional heat supply from outside B becomes possible: the start-up phase of the installation. Since the hydrogenation reaction in the hydrogenation chamber 5 proceeds exothermically, the heat exchange jacket .11 after the start-up period of the installation switches and is used as cooling chamber with circulating coolant for heat removal. In the preparatory chamber 2 and in the hydrogenation chamber 5, a very high pressure is created up to 500 bar. Therefore, it is necessary that the outlet from the hydrogenation chamber 5 be made hermetically closed by means of a valve 10 opening when a predetermined pressure is exceeded. Hydrogenation products; after they pass the valve, 10, they enter the hot separator 22, which separates the solid and liquid hydrogenation products through the valves 23 and 24. Thereafter, the hydrogenation products are further processed in a known manner. FIG. 2 shows an installation with a vertically arranged hydrogenation chamber 5. When the hydrogenation chamber 5 is located vertically in the preparatory chamber 2, the shaft 4 of the friction element 3 rotates the rotor 8 located in the hydrogenation chamber 5 through rotation. The rotor 8 is mounted on both sides in bearings 26 and 27. This arrangement of the hydrogenation chamber 5 and preparatory chamber 2 requires little space and is therefore preferable in certain cases. Example. The installation is heated to. Then, the friction elements and the rotor are driven into the movement by means of the drive unit and, through the openings of the cell feed gateway, coal is crushed into grains of 0.1 mm in size, together with the catalyst pre-mixed with coal. The catalyst consists of 1.5% ferrous sulphate and 2% of Bayer's mass consisting of%: FejO - 48; 20; SiOj - 0.2; TtOj, as well as oxides Mn, Ca, Md, Na, K. 6. The preparatory chamber has a progressively increasing temperature from 250 to 450 ° C. Due to the rotational movement of the friction element, the coal is compacted and the pressure at the outlet of the feed chamber is 398 Then the plasticized carbon in this way continuously feeds the hydrogenation chamber and treats with hydrogen through unnumbered mixing nozzles. The pressure in the chamber of hydrogenation is 356 atm, and as a result of the exothermically proceeding reaction, the temperature is established within 4pO-430 ° C. The mixture leaving the chambers is trapped in the separator. The analysis of products of the separator gives the following values.

The unit is temperature adjustable. At the same time, the friction element with a rotor located on it is driven by means of a drive unit and coal is fed into the chamber using a lock lock, crushed to a grain size of 0.5 mm, together with a catalyst pre-mixed with coal.
