- W2384472243 abstract "In order to reduce or avoid the influence of low temperature oxidation and enrich low temperature oxidation theory of coal,Mesozoic Jurassic bituminite in the Aiweiergou Mine of Xinjiang Coking Coal Group was taken as a research object to investigate the influence on its structure and thermodynamic properties during low-temperature oxidation in this paper. Directly detected the FTIR of vitrinite and inertinite with attenuated total reflectance micro-Fourier transform infrared( ATR-FTIR) spectroscopy was more convenient than the traditional method which firstly separated vitrinite and inertinite from coal and then detectd their FTIR. Vitrinite and inertinite have the same radical groups.Radical groups' content in vitrinite is significantly higher than that in inertinite. After peroxide oxidation,the calorific value of coal decreases; peak intensity of —OH and methylene increases at first and then reduces; peak intensity of carbonyl reduces at first and then increases. The vitrinite has little changes. In inertinite,the peak intensity of —OH and carbonyl reduces,carboxyl relatively unchanges,peak intensity of aromatic ring and C—O—C increase slightly.Hydrogen peroxide oxidation alteres less the thermodynamic properties of the bituminite. Thermogravimetric curve slightly moves to low temperature zone after peroxide oxidation." @default.
