WebGas Adsorption Theory Poster - Home - Micromeritics WebApr 23, 2024 · According to the results of low-temperature nitrogen adsorption experiment, the pore specific surface area can be calculated by BET equation when P/P0 is between 0.05 and 0.35. Moreover, the pore volume and pore diameter distribution of coal can be analyzed by BJH equation when P/P0 is greater than or equal to 0.4 .

WebBarrett Joyner Halenda (BJH) method. HISTORICALINTRODUCTION From the standpoint of classical thermodynamics, the physisorption (i.e. physical adsorption) of a non-reactive vapour by a porous solid is a reversible process. The general form of the physisorp-tion isotherm for a given vapour solid system at a temperature T is: (1) can an ira account be margined
