Thermal plasma pyrolysis of used tires for the production of syngaswas investigated experimentally and the following conclusions wereobtained: 1. A series of experiments have shown that tire waste can bepyrolyzed in a plasma reactor to produce combustible gas, such asC{sub 2}H{sub 2}, CH{sub 4}, C{sub 2}H{sub 4}, H{sub 2}, CO. The combustion heat value of the produced gas is about 4-7 MJ/m{sup 3}, which is higher than that of blast furnace gas and reforming gas from coals. 2. Zinc oxidecan be captured during pyrolysis by both high temperature filters andlow temperature filters in the quenching chamber. The pollution gases,such as SO{sub 2} and NO{sub x}, are at relatively low levels, about 100-300ppm. 3. Increasing the tire injection quantity will increase theconcentration of hydrocarbons, increase the combustion heat of thepyrolysis product, and decrease the concentration of metal oxide. Withsteam injection, it produced a large quantity of hydrogen and carbonmonoxide with lower concentrations of C{sub 2}H{sub 2}. The combustion heatis slightly lower with steam injection than that without it. 4. Neitherpolychlorinated biphenyls (PCBs) nor p-aminohippuric acid (PAH) weredetected in the ashes. 8 refs., 11 figs., 4 tabs.
