Abstract

Abstract

En 中文
• A coal macromolecular model was constructed using FTIR and 13C NMR data. • Competitive adsorption behaviors of O2, N2 and CO2 in coal pores were revealed. • Diffusion characteristics of gases in coal were analyzed by molecular dynamics. • Inert gases reduce oxygen adsorption through competitive adsorption mechanisms. • The microscopic mechanism of inert gas inhibition of coal oxidation was clarified.
