CARBON MINERAL ADSORBENTS - NEW-TYPE OF SORBENTS .2. SURFACE-PROPERTIES AND METHODS OF THEIR MODIFICATION

Chemical structure and morphology of carbon deposits contained in comp lex carbon-mineral adsorbents prepared by pyrolysis of different subst ances on the surface of mineral adsorbents such as silica gels, alumin ium oxide, aluminosilicates, porous glasses, etc. have been discussed. The morphology of the carbon deposit depends on the course of the pyr olysis reaction and determines the surface properties of complex adsor bents and the possibilities of their practical utilization as sorbents and catalysts. The methods of modification of adsorption properties o f such adsorbents prepared on technical and laboratory scales were als o presented. Thermal properties of carbon-mineral adsorbents in atmosp heres of different gases were also discussed.
