Abstract: The invention presents a method for predicting volatile organic compounds (VOCs) adsorption capacity via filling adsorption, in the domain of exhaust gas treatment. Utilizing two or more porous materials with concentrated pore size distributions as model adsorption materials, it identifies the critical pore size for filling adsorption under specific conditions. Filling adsorption operates via volume filling, linking adsorption capacity to density and pore volume. Conversely, non-filling adsorption relies on surface covering mechanisms, correlating adsorption capacity with specific surface area. By establishing a linear equation using pore volume and specific surface area, solved with known model material parameters, it accommodates pore size variation and pressure influence on adsorption capacity. This equation predicts VOCs adsorption capacity and isotherms based on the adsorption material's pore structure.
