为了深入分析温度对煤体瓦斯吸附特性的影响,利用自行研制的煤层气高压吸附装置,开展不同温度条件下的含瓦斯煤体吸附试验。试验结果显示:吸附压力对煤体吸附性能的影响具有明显的阶段性;吸附常数a随着温度的增加呈现出先增大后减小的变化特征,具有明显的阶段性;吸附常数b值随温度的增加逐渐降低,但降低幅度逐渐变缓,并最终趋于恒定。 In order to deeply analyze the influence of temperature on the gas adsorption characteristics of coal, a self-developed high pressure adsorption device of coalbed methane was used to carry out the adsorption test of gas containing coal under different temperature conditions. The experimental results show that the adsorption pressure affects the adsorption properties of coal obviously. The adsorption constant a increases with the increase of temperature and then decreases. The b value of adsorption constant changes with the increase of temperature Increase gradually decreased, but the rate of decrease gradually slowed down and eventually tended to be constant.
