温度对煤氧吸附模型的适应性研究
The Adaptability of Temperature on Coal and Oxygen Adsorption Model
摘要
Abstract
This paper selected Chengzhuang Mine No.9 coal as anthracite samples.Effect of temperature on coal oxygen adsorption at 25,30,35,40 ℃ conditions was studied by adsorption constant measuring apparatus.The results show that,under the condition of critical spontaneous combustion temperature (25～40 ℃) and lower pressure (p≤2.5MPa),the adsorption of coal for oxygen has an inhibitory effect with the increase of temperature.The fitting effect of Langmuir model is better in the temperature range of 25～35 ℃,and worst at 40 ℃;the fitting effect of Brunauer-Emmett-Teller is the worst at 25 ℃,and the fitting error becomes smaller with the increase of temperature while fitting effect is getting better and better;the average relative error of the Dubinin-Radushkevich model model is smaller and the standard deviation is the smallest in the experimental temperature of 20～40 ℃,Dubinin-Radushkevich model model explains the adsorption mechanism of anthracite is the most reliable and authentic.This research can provide a theoretical basis and reference for the air for coal-bed methane.关键词
