Abstract

Abstract: In order to study the mechanism and degradation efficiency of hydroxyl radical oxidation of methane，nitrogen-balanced standard methane was used as model feed of coal-mine gas. Based on the free-radicals chain reaction properties of Fenton reagent oxidation, the two-phase reaction of gas-liquid and oxidant were full contact mixed in the self-designed bubbling reactor. through the research on the concentration variation of methane, the effects of H2O2 concentration, Fe2+ concentration, and reaction temperature on methane degradation efficiency were investigated. Therefore, for the further exploration of methane degradation in the practice production and application, important reference for green treatment technology of mine gas was provided.

Key words: hydroxyl radical, degradation, coal-mine gas, Fenton reagent, methane
