METHOD OF DETERMINING REACTION SURFACE OF CARBON MATERIALS Russian patent published in 2012 - IPC G01N15/08 

FIELD: physics.

SUBSTANCE: method of determining the reaction surface of carbon materials involves conducting processes for adsorption from a stream of a mixture of helium and an adsorbate at different temperatures. The method also involves desorption of the formed reaction products into the stream of the mixture by heating and measuring concentration of reaction products in the stream of the mixture. The adsorbate used is oxygen. Adsorption is carried out at temperatures ranging from 20°C to 500°C and desorption is carried out by heating to temperature 900°C.

EFFECT: method for realising a dynamic technique for thermal desorption, which takes into account physical and chemical sorption of the adsorbate with respect to the test sample, which enables to determine the reaction surface of carbon materials.
