Э : 10521644The invention relates to methods for processing carbon-containing gas, in particular, to a method for continuous gasification of coal. The known method of continuous gasification of coal in a lined peakor with a molten metal, BKJTO, which feeds coal and acidic gas of a second gas into the reactor below the level of the molten metal through pipes introduced into the molten metal and the subsequent gasification f 1 J A known method is partly broken. for the replacement of pipes and the poor quality of the gas produced, which adversely affects: the productivity of the process: The purpose of the invention is to increase the productivity of the process. This goal is achieved by the fact that according to the method of continuous gasification of coal in a lined reactor with molten metal, including the supply of coal and oxygen-containing gas to the reactor, is lower than the level of the molten Metal and subsequent gasification, coal and oxygen-containing gas will be poured into molten metal. centrally installed pipes, the output nozzles of which are located at the level of Lining C to reduce wear of the pipe for. oxygen-containing taa-a is supplied. 7-7 straight or liquid hydrocarbons through a pipe located close to the pipe to supply oxygen to the carrier gas, or gaseous or liquid hydrocarbons are introduced into the pipe to feed carbon. Before serving in the molten metal, the coal is mixed. , with oxygen-containing gases in the pipe for iodine oxygen-containing gas flow. coal is reported to rotate. PRIMER 1 The process of continuous gasification is carried out in a 20-meter futher-reactor with four nozzles in the bottom, each of which is made up of three concentrically installed pipes whose outlets are located at the lining level. The central tube of each nozzle with a diameter of 10 mm in light is used to supply coal dust. An annular gap between the inner and second pipes 3 mm wide serves to supply oxygen, and propane is fed through the outer annular gap between the second and third pipes 1 mm wide. The reactor contains 30 tons of molten iron, which contains 1.5-2.5% carbon. . The temperature of the melt is 137 ° C-1450 ° C. 12,000 kg / h of coal, 10,800 tons of ice, 216 nm3 / H of propane are introduced into the molten 4-melts. At the same time, 25,000 are obtained. gas containing,%: CO 65.5 G Yy 34.2 and CO 0.3. For one month (720 h), the nozzles evenly heat 200 mm in diameter without disrupting the gasification process. When the specified period expires, the process is stopped. To replace the nozzles. A and M 2. Example 1 is repeated with the difference. That the reagents are fed to the nozzles located in the side wall of the reactor below the metal level. At the same time, 25,000 gases are obtained containing,%: CO 65.51 T | H 34.3 and CO, 0.2. The process is carried out without; any violations within 740 hours. Rome, p. 3. Example 1 is repeated, with the difference that the reagents are supplied by yo soplam, each: of which the issue is 6-1-1 yen. From two district-located pipes. At the same time, coal is supplied along the inner pipe: PROPANO, and YO gives oxygen to the annular gap between the inner and outer pipes. 25000 nm3 / h of gas of the following composition are obtained:% 5 CO 65.5 / Bg 34.2 and CO 0.3. The process is carried out without any kind. For: bobo.ch.-;: -.: .-,::: .... In Me p 4, Example 3 is developed with the difference that rotational motion is absorbed by the flow of coal. In this case, g -s 25,000 dm3 / h times the composition,% CO 65.5j H2 and COg are obtained during the course of h. With Me p 5 Example 1 is repeated. with TOH pasHHitei - - that the process was carried out in a 20-meter lined reactor with a syringe: by using four nozzles in the reactor, each of which was made of co-centrically installed pipes.

On that occasion, in order to place a yropaya yo yar, a yellow gas is fed to its annular gap. With this s. Leaks 720 j receive 25,000 gas containing.
