Pyrolysis characteristics of typical organic components of medical waste were studied by using a fixed bed tubular reactor.The composition and volume fraction of pyrolysis gas were measured by on-line gas analyzers.The effect of pyrolysis temperature was also analyzed.The results indicated that the material characteristics and the final pyrolysis temperature had great effects on the release and volume fraction of pyrolysis gas.The results indicated that the absorbent cotton and bamboo had a lower initial temperature than polypropylene when pyrolyzed.The maximum of gas generation rate and the gas yield increased with the pyrolysis temperature

as well as the proportion of the combustible gas in the total gas products.
