Simplified De Bore Model of Coal Adsorption Gas

Abstract:

With respect to the problems existed in the description of the adsorption characteristics of super-low rank and super-high rank coals using the conventional Langmuir adsorption model, in this paper, We first introduces the De Bore adsorption model into the coal seam gas adsorption, and utilizes the results of the ab initio calculation of quantum chemistry result and the isothermal adsorption test statistical results, simplifies the De Bore model equation. The new adsorption model is more suitable for describing the gas adsorption characteristics of the whole coal ranks. This new model has the stronger function and wider suitable scope than the Langmuir adsorption model.
