Ledovs'kykh O. Simulation of kinetics of carbon adsorbents porous structure formation during the steam-gas activation

To describe kinetics of active carbons porous structure formation during activation the mathematical random pore model and its modifications that take into account pore size distribution, pore overlapping, new pore formation (nucleation effect), biporous building of active carbons and ash content has been developed. The proposed model adequately describes evolution of structural-sorption performances of synthetic and natural active carbons during their activation and shows good agreement with experimental data. For calculation on developed model and determination of active carbons porous structure characteristics from adsorption experimental data interactive computer programs has been developed. Practically important result of the work is the possibility of prediction of active carbons porous structure development laws and optimization of activation process. The offered approach allows deciding problems of directional synthesis of active carbons with optimal porous structure.
