Abstract: | A carbon adsorbent obtained by a procedure analogous to reverse burn coal gasification is being evaluated in our laboratory. This low surface area carbon adsorbent shows considerable promise as a fractionation medium for a variety of organics. The performance of the adsorbent compares favorably to the highly specialized carbon adsorbents such as PX-21 (Amoco Corp.). The adsorbent also has considerable potential for treatment of wastes containing organochlorine compounds. The adsorbent shows good adsorption capacity and can hold as much as 50% (w/w basis) of organic sludge while maintaining a relatively dry, granular character. Furthermore, this waste-loaded adsorbent is amenable to highly efficient self-sustained thermal degradation. Degradation efficiencies approaching 99.99 percent have been achieved for such recalcitrant organics as polychlorinated biphenyls and tetrachlorodibenzo-p-dioxins. |
