The effect of the yield and composition of the liquid products on the formation of the porous structure of semicoke is examined. The more complete desorption of the low molecular weight components in a stream of water vapour up to 300Β°C leads to a considerable increase in the total pore volume and t
Activated carbons with degrees of burn-off between 20% and 80% have been prepared from a semianthracite char by gasification in steam at 1123 K. The adsorption isotherms of nitrogen at 77 K and CO, at 273 K have been determined. The pore size distribution has been calculated from t plots, and heliu
