利用高温高压气体吸附分析仪,研究了不同压力阶段条件下温度对瓦斯解吸规律的影响,得到了各个压力段的瓦斯累计解吸量随时间变化的实测曲线,进而得到累计解吸量与时间的函数关系式。实验结果表明:在各个解吸压力段内,不同温度的瓦斯累积解吸量不同;在相同压力条件下,温度越高,煤粒瓦斯解吸越容易;各个压力段内,不同温度的瓦斯累积解吸量与时间的关系均能拟合成统一的函数关系式。
The effect of temperature on gas desorption law under different pressure stages was studied by using high temperature and high pressure gas adsorption analyzer. The measured curves of cumulative gas desorption amount over time in each pressure section were obtained. As a result, the cumulative desorption capacity as a function of time was obtained formula. The experimental results show that the gas desorption amounts of gas at different temperatures are different in each desorption pressure section. Under the same pressure conditions, the higher the temperature is, the easier the gas desorption of coal particles will be. The gas desorption amounts at different temperatures and The relationship between time can be fitted into a unified functional relationship.
