摘要
Pyrolysis treatment of waste tires was studied in a capacitively-coupled radio frequency (RF) plasma reactor. Using RF input power between 1600 and 2000W and a reactor pressure between 3000 and 8000Pa, a reactive plasma environment with a temperature between 1200 and 1800K can be reached. Under these conditions, pyrolysis experiments with tire powder showed that two product streams were obtained: a combustible gas and a pyrolytic char. The main gaseous components were H2, CO, and CH4. When adopting double sets of electrodes in this plasma reactor, the gas yield and concentrations of H2 and CO can be enhanced. The energy utilization efficiency of this RF plasma pyrolysis reactor system was also analyzed.
