【摘要】 为了深入了解煤氧复合机理,对煤低温阶段的吸氧过程进行了理论分析,并利用色谱吸氧法对煤低温阶段的吸氧量进行了测定。结合测试结果,分析了煤吸氧量随煤变质程度、温度的变化趋势,阐述了煤物理吸氧和化学吸氧之间的关系及其在煤自燃过程中的作用,并对现行色谱吸氧鉴定法进行了分析。更多还原

【Abstract】 In order to obtain a detail complex understanding of the coal oxygen adsorption mechanism, the theoretical analysis on the coal oxygen adsorption at low-temperature period was conducted.The chromatograph oxygen adsorption method was applied to measure the oxygen adsorption value at low-temperature period.In combined with the measured results, the paper analyzed the variation trend of the oxygen adsorption value with the coal metamorphic degree and temperature.The relation between coal physic oxygen sorption and chemical oxygen sorption and their effect in the coal spontaneous combustion process were introduced.The paper also analyzed the present chromatograph oxygen adsorption certification method.更多还原
