METHOD FOR PRODUCING SYNTHETIC GAS

The invention relates to the technology of hydrocarbon processing and more particularly to the production of synthesis gas from gaseous hydrocarbon raw. The object of the present invention is to provide an improved method for producing synthesis gas, which includes combustion of the mixture of raw hydrocarbons and air at alpha = 0.5 DIVIDED 0.8 and oxidation of hydrocarbons upon compression stroke of the piston in the cylinders of the modified internal combustion engine, expansion and cooling of the products during the piston stroke to the bottom dead center, output of the products containing synthesis gas from the reaction volume upon the piston stroke to the top dead center, inlet of a new portion of the working mixture upon the piston stroke to the bottom dead center differing by that a mixture of raw hydrocarbons with air preheated to 200 - 450 DEG C is fed into the cylinders of the modified internal combustion engine, and the mixture is compressed until self-ignition takes place and a temperature of 1300 - 2300 DEG C is maintained over a time period of 10 - 10s, and the cycle being repeated with a frequency exceeding 350 min. In frameworks of this method, the use of methane, ethane, and other gaseous hydrocarbons as the raw materials obtained, in particular, through separation of the broad fraction of light hydrocarbons from the associated gases makes it possible to improve the ecological situation in the regions of oil production and processing. The specific productivity of the method is SIMILAR 2.5 times higher compared to the known method.
