摘要：
 综合考虑努尔森（Knudsen）扩散和表面扩散，理论上推导出适用于无机膜气体分离的温度-压力-气体渗透率方程。方程包含4个有物理意义的参数A、 B、 ?和?。A和B与无机膜的性能有关。?显示温度的影响。?显示压力的影响。基于无机膜气体分离与煤岩煤层气吸附的相似性，将温度-压力-气体渗透率方程衍变成仍然有4个参数（A、 B、 ?和?）和相同的数学形式的温度-压力-气体吸附方程。用松藻煤电公司8#煤层煤样的系列兰格缪尔等温吸附实验数据来验证温度-压力-吸附方程的适用性。平均相对偏差计算法和作图法都验证温度-压力-吸附方程的适用性。
 Considering the Knudsen diffusion and surface diffusion, a modified diffusion equation for gas permeation through microporous media was obtained theoretically as a function of both temperature and pressure. The diffusion equation contains four parameters (A, B, ? and ?) with physical meaning. A and B reveal the properties of inorganic membrane. The pressure effect ? on the surface diffusion stems from the adsorbate concentration. The temperature effect ? is related to the relative energy difference between the minimum potential energy and the activation energy for an adsorbed molecule. There are high degrees of similarity between inorganic membrane gas separation and coal seam gas adsorption. A temperature-pressure-adsorption equation was, therefore, evolved with the same mathematical formula and four parameters. The Langmuir series isothermal adsorption data of Songzao 8# coal seam are used to verify the applicability of temperature-pressure-adsorption equation. Both the average relative deviation calculation method and the mapping method verify the applicability.
