METHOD OF PREVENTING IGNITION, COMBUSTION AND EXPLOSION OF HYDROGEN-AIR MIXTURES Russian patent published in 2013 - IPC C09K15/04 

FIELD: chemistry.

SUBSTANCE: invention relates to fire and explosion safety and can be used in production, storage and transportation of hydrogen, in factories associated with formation of hydrogen as the main and/or by-product. The method of preventing ignition, combustion and explosion of hydrogen-air mixtures involves adding an inhibitor to the hydrogen-air mixtures, the inhibitor being a mixture of halohydrocarbons C₂F₄Br₂+CF₃Br and/or C₂F₄Br₂+CF₃l and/or C₂F₄Br₂+C₂F₃ClBr₂ and/or C₂F₄Br₂+C₂F₃Cl₃. The inhibitor is added in amount ranging from 6 vol. % to 20 vol. % of the volume of the mixture.

EFFECT: high efficiency of preventing ignition, combustion and explosion of hydrogen-air mixtures, low chemical aggressiveness and toxicity, wider temperature range and cheaper process of preventing ignition.
