METHOD OF MEASURING POROSITY OF PARTICLES OF BULK MATERIALS Russian patent published in 2014 - IPC G01N15/08 

FIELD: testing technology.

SUBSTANCE: invention relates to the field of testing and determine the properties of the materials. The method of measuring porosity of the particles of bulk materials can be reasonably used for production of granulated catalysts, sorbents, and to determine the properties of porous materials for various purposes. The method of measuring the porosity of the particles of bulk material comprises measuring the true density of the particles of bulk material and the pressure differential across the material layer in the regimes of gas filtering and fluidisation generated by changing the gas flow rate, according to which the porosity of the particles is judged.

EFFECT: ease of implementation, lack of use of toxic substances, scarce materials, as well as providing the possibility of rapid measurements of properties of hydrophobic bulk materials with pronounced sorption properties and developed surface.
