APPLICATIONS FOR ACTIVATED CARBONS FROM WASTE TIRES - NATURAL-GAS STORAGE AND AIR-POLLUTION CONTROL

Natural gas storage for natural gas vehicles and the separation and re moval of gaseous contaminants from gas streams represent two emerging applications for carbon adsorbents. A possible precursor for such adso rbents is waste tires. In this study, activated carbon has been develo ped from waste tires and tested for its methane storage capacity and S O2 removal from a simulated flue-gas. Tire-derived carbons exhibit met hane adsorption capacities (g/g) within 10% of a relatively expensive commercial activated carbon; however, their methane storage capacities (V-m/V-s) are almost 60% lower. The unactivated tire char exhibits SO 2 adsorption kinetics similar to a commercial carbon used for flue-gas clean-up. Copyright (C) 1996 Elsevier Science Ltd
