煤的温压吸附试验方法与等温吸附试验方法比较研究

Comparative Study on Temperature Pressure Adsorption Test Method and Isothermal Adsorption Test Method for Coal

为了研究煤的温压吸附试验方法在煤层气吸附方面的可行性,本文对煤的温压吸附试验方法与煤的高压等温吸附试验方法进行了比较研究。分别取12个、10个、8个、和6个温压吸附试验点作为四组不同温度和相应不同压力作为温压吸附试验点,记为V_(实测)。使用温度-压力-吸附方程(Temperature-Pressure-AbsobingEquation(TPAE)),将方程转化为二元一次方程后进行线性回归计算其余三个参数,将所得的四个参数记为V_(计算)。通过计算_(实测)与V_(计算)之间的平均相对误差和标准偏差以衡量温压吸附试验方法的可行性。

In order to study the feasibility of the temperature and pressure adsorption test method of coal in the adsorption of coalbed methane,this paper compares the temperature and pressure adsorption test meth-od of coal with the high-pressure isothermal adsorption test method of coal.Take 12,10,8,6 temperature and pressure adsorption test points as four sets of different temperatures and corresponding pressures as the temperature and pressure adsorption test points,denoted as V measured.Use the Temperature Pressure Ab-sorption Equation(TPAE)and convert the equation into a binary linear equation,then perform linear re-gression to calculate the remaining three parameters.Calculate the adsorption capacity of the four parame-ters obtained,denoted as V.The feasibility of the temperature pressure adsorption test method is evaluated by calculating the average relative error and standard deviation between V measurement and V calculation.
