FIELD: removal of hydrogen from gas mixture. SUBSTANCE: device for removal of hydrogen from gas mixture with a catalytic device and simultaneous removal of harmful substances contained mainly in the form of aerosols, appearing, for example, at some damages of the nuclear reactor. The catalytic device for removal of hydrogen is made as a shaft and therefore, the heat arising because of the catalytic action results in creation of a hood effect inside the shaft and thus in creation of a pressure differential, due to which the use of filters in the shaft interior becomes possible so as to catch the harmful substances contained in the gas flow. EFFECT: facilitated procedure. 10 cl, 8 dwg
