摘要
用容量法测定了不同温度下甲烷在无烟煤及其炭化样上的吸附特性。结果表明甲烷在无烟煤及其炭化样上吸附平衡时间分别由５０℃时的５ｈ和３ｈ增加到－２１℃时的２５ｈ和１６ｈ，吸附热分别为１５ＫＪ／ｍｏｌ和１２ＫＪ／ｍｏｌ。
The adsorption characterizations of methane on anthracite coaland its char under different pressure and temperature were measured by using ofvolumetric method. The experimental results have shown when methane is adsorbedon the coal and the char,the adsorption heat is 15kJ/mol and 12kJ/mol,and the ad-sorption time reaching at equilibrium changed from 5 hours and 3 hours at 50 ℃ to25 hours and 16 hours at-21℃,respectively.
