  • Process for characterization of micro and meso porous materials
    Patent number: 9274040
    Abstract: A process for characterizing micro, meso, and/or macro porous materials is provided. The process includes providing a volumetric and/or gravimetric adsorption system, the adsorption system having an adsorption chamber and a probe gas at a first temperature. In addition, a porous material to be characterized is provided and placed within the adsorption chamber. Thereafter, a porosimetry run is conducted on the porous material. The porosimetry run includes: (a) selecting an uptake target value; (b) selecting a target interval bounding the target uptake target value; (c) adjusting pressure within the adsorption chamber in order for the porous sample to reach the target uptake value; (d) adjusting pressure within the adsorption chamber until the pressure within the adsorption chamber is within the target interval for a predetermined amount of time; and (e) repeating steps (a)-(d) until the porosimetry run is complete.
