A Preliminary Study of the Plasma Pyrolysis of Waste Tyres

Thermal plasma pyrolysis of waste tyres for frcovering energy was performed in a nitrogen plasma reactor.The main gaseous products were identified by chromatography as H2,CO,CH4,C2H2 and so on .From a series of experiments,the effects of the process parameters of thermal plasma pyrolysis were investigated.Under our experimental conditions with steam injection,the total contents of H2 and CO reached up to 38.3% in the gas product,C2H2 up to 4%,and the maximum calorific value of the pyrolysis gas was 8.96MJ/m^3,The results indicated that plasma-assisted thermal decomposition of waste tyre particles may be a useful way for recovering energy and useful chemicals.
