Effects of coal molecular structure on adsorption and diffusion behaviors of coalbed methane

中文摘要英文摘要

对煤的芳香单元延展度、芳香单元堆砌层数以及包括不同缺陷和含氧官能团类型的表面结构对煤层气吸附与扩散的影响进行了研究。采用Monte Carlo模拟方法及分子动力学模拟方法分别得到了煤层气的吸附量与扩散系数,模拟温度为303 K,压力为10 MPa。研究结果表明,单位质量的煤对甲烷的吸附量随着芳香单元堆砌层数的增加而降低,缺陷和含氧官能团的存在不利于甲烷的吸附。甲烷的扩散随着芳香单元延展度的增加呈现出一个N形的复杂变化过程,单缺陷和羰基的存在有利于…查看全部>>

The effects of microcrystal structures, such as the extension of basic structural unit (La) and the number of basic structural unit (N), as well as the surface structures including different types of defects and oxygen-containing functional groups, on the adsorption and diffusion of coalbed methane were investigated. The adsorption amounts were simulated by using the Monte Carlo (MC) method, and the diffusion coefficients of coalbed methane were simulated by…查看全部>>
