二氧化氯作用下的煤吸附性变化及其大分子结构响应
Variations in Adsorption and Macro-Molecular Responses of Coals Treated with Chlorine Dioxide Solution
摘要
Abstract
By methods of chlorine dioxide solution immersion, isothermal methane adsorption and X-ray diffraction, new principle of coal reservoir stimulation and its possible geoehemical mechanism on the macro-molecular structure level were discussed. The result shows that the coal adsorption constant changes obviously and the gas saturation and critical desorption pressure are improved in different degrees after immersed, but the increase efficiency is controled by coal rank. After treated by chlorine dioxide, depolymerization appears for coal macro-molecular structure unit in different degrees, and coal macro-molecular structure and its adsorptivity responses synchronously. Other organics containing benzene ring exists in residual chlorine dioxide solution, and the depolymerization degree is related to eoalification degree. Experimental results indicate that the coal molecular structure changes after immersion and leads to the surface properties variation, which influences the coal adsorption capacity on methane and the desorption potential trend of coalbed methane.关键词
