Modelowanie właściwości węgla aktywnego o różnej geometrii ziaren w reakcji karbonizatu z parą wodną
Modelling the Properties of Active Carbons of Various Particle Geometries in the Reaction of Carbonisate with Steam

Summary/Abstract: The porous structure of cylindrical and ring-shaped carbonaceous material was developed by partial steam gasification. Micropore and mesopore structures of active carbons with various burn-offs were evaluated with nitrogen adsorption/desorption isotherms. The parameters of the Dubinin-Radushkevich equation were calculated, as were surface mesopores using Dollimore and Heal method and the micropore size distribution by the Horvath-Kawazoe equation. The results of textural research showed that more uniform micropore structure and better mechanical properties were found for the ring-shaped active carbons.
