摘    要:通过对近几年来采自不同地区,各种煤级140个煤样的平衡水分,等温吸附特性,煤岩组成和煤质的综合研究,揭示他煤在平衡水分条件下等温吸附特性的变化规律,探讨了其影响因素。结果表明,煤的等温吸附特性主要受煤级影响,随着煤级增高,表征煤最大吸附能力的兰米尔体积逐渐增大,这一变化规律与以前对于煤样的研究结果明显不同;

关 键 词:  等温吸附特性  平衡水分  煤级  矿物  显微组分

Abstract:The comprehensive research is made on equilibrium moisture, isothermal adsorption feature, proximate analysis and coal petrology for approximate 140 coal samples with different rank and from different places. The variable pattern of isothermal adsorption feature of coals in equilibrium moisture and approached its impact factors are revealed It has been concluded that isothermal adsorption feature is mainly influenced by coal rank Along with coal rank, Langmuir volume indicating maximum adsorption capacity of coal gradually increases This pattern is very different from the previous results got from dry coal samples On the other hand, mineral and maceral contents also make certain impacts on isothermal adsorption feature
Keywords:coal  isothermal adsorption feature  equilibrium moisture  rank  minerals and macerals
