Effects of equilibrium time and adsorption models on the characterization of coal pore structures based on statistical analysis of adsorption equilibrium and disequilibrium data

Low-pressure CO2 adsorption is an important tool for quantitatively characterizing the micropore characteristics of porous materials. While only adsorption data obtained at adsorption equilibrium will ensure the accuracy of the method. In this paper, 82 sets of CO2 adsorption equilibrium and disequilibrium data of coal samples with different particle sizes were investigated, and the influence of equilibrium criterion and data analysis methods on...
