Porous structure of carbonaceous adsorbents from peat carbonized in the presence of aluminum chloride

The formation of the porous structure of carbonaceous adsorbents obtained by the steam-air activation of the products of the carbonization of peat in the presence of aluminum chloride has been investigated. The influence of the temperature of carbonization of the peat, of the degree of burn-off of the semicoke in the process of steam-air activation, and of the amount of aluminum chloride added on the porous structure and the physicochemical properties of the adsorbents have been studied. The change in the dimensions of the pores and the ratio of the varieties of pores in the process of steam-air activation of the peat semicoke has been investigated by the method of small-angle scattering of X-rays. The optimum conditions for the carbonization and activation process in the production of carbonaceous adsorbents from cottongrasssphagnum peat have been determined.
