为探索Langmuir方程吸附常数与温度之间的变化规律,利用HCA型高压容量法吸附装置,针对重庆能源投资集团松藻煤电公司8^#煤层煤样,分别在温度为30℃、40℃、50℃、60℃、70℃条件下进行了煤对瓦斯的等温吸附实验。结果表明,当温度一定时,吸附量随瓦斯压力的升高逐渐增加并趋于一稳定值;压力一定时,随着温度的升高,煤的瓦斯吸附量呈下降趋势。
In order to discover the variation law between the absorption constant of the Langmuir equation and the temperature, the absorption device of the HCA high pressure volumetric method was applied to the coal and gas isothermal adsorption experiment on the coal samples from No. 8 seam of Songzao Coal and Electric Power Company, Chongqing Energy Investment Group under the temperature conditions of 30 0℃ , 40 ℃, 50 ℃ , 60℃ and 70 ℃ individually. The results showed when the temperature was certain, the absorption value would be steadily increased with the gas pressure increased and would be at a stable value. When the pressure was certain, with the temperature increased, the gas absorption value from coal would be steadily declined.
