METHOD OF PRODUCING COLD OXYGEN GAS AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2010 - IPC C01B13/02 

FIELD: chemistry.

SUBSTANCE: oxygen generator can be used as a more efficient compact standalone source of oxygen gas for enabling people to breath, mainly during accidents and emergency situations. The generator has a housing which has one or more outlet openings, a solid charge of oxygen-generating material which is placed in a combustion chamber lying in the housing and having one or more outlet openings. Between the outer surface of the combustion chamber and the housing of the generator there is a multifunctional active element which has a porous gas-permeable structure and whose material is selected from a group of peroxides and superoxides of alkali and alkali-earth metals. The generator has a device for igniting the charge and a filter for removing particles from the obtained oxygen.

EFFECT: increased specific output of oxygen with simultaneous reduction of temperature and increase in purity of the generated oxygen, reduction of temperature of the housing during and after operation of the generator, longer operation time of the generator and increased safety during its operation.
