The invention is used in gas chemistry for producing hydrogen-containing gas on the base of CO and H 2 mixture (syngas) from natural gas and other hydrocarbon gases. The object is to suppress side reactions resulting in soot formation when conducting the process in high productivity mode, and also to provide for an uncomplicated reactor design while maintaining compact dimensions thereof. The method for producing hydrogen-containing gas comprises mixing natural gas with oxygen, partially oxidizing the natural gas with oxygen at a temperature ranging from 1,300°C to 1,700°C to obtain hydrogen-containing gas, and cooling a stream of the obtained hydrogen-containing gas. The cooling is performed until the temperature drops below 550°C at a rate above 100,000°C/sec. The reactor comprises successively arranged in the course of production process: a means for supplying natural gas and oxygen, a natural gas and oxygen mixing zone, a reaction zone for carrying out partial oxidation of natural gas with oxygen to obtain hydrogen-containing gas, and a cooling zone for cooling a stream of the obtained hydrogen-containing gas/ The cooling zone is provided with a cooled body of revolution to enable intensive cooling the stream of the hydrogen-containing gas by contacting thereof with the body of revolution.
