DEVELOPMENT OF PROPERTIES WITHIN PARTICLES OF ACTIVE CARBONS OBTAINED BY A STEAM ACTIVATION PROCESS

It has been shown that there exists a correlation between the properties of samples obtained via an abrasion technique and the position within the active carbon particle. Detailed experimental investigations have revealed radial heterogeneity of the porous structure, the character of the surface, and burn-off of the carbonaceous material within steam-activated particles. A change of the properties throughout the particles is experimental proof that the steam activation process occurred in a region characterized by significant resistance to heat and mass transfer.
