T/CPCIF 0140-2021 Catalyst carrier— Determination of surface area and pore volume for quasi-thin-water aluminit— Nitrogen adsorption method (English Version)
The specific surface of the sample in the gas system (the specific surface area of the external and internal pores of the particle) will undergo physical adsorption at low temperature. When the adsorption reaches equilibrium, the equilibrium adsorption pressure and the amount of adsorbed gas are measured, and the specific surface area is calculated according to the BET parameter equation; When the relative pressure p/p0=0.98, the sample pore volume is calculated based on the adsorbed nitrogen volume.
