| 摘 要： | The gaseous products of co-pyrolysis of waste tires and biomass under DC arc plasma condition were investigated. The results showed that the volumetric concentration of acetylene in carbon-containing gases obtained when waste tires, biomass and coal were separately pyrolyzed was 14.6%, 13.7% and 10.6% respectively when the parameters experimental run were 150 A of electric current, 310 V of voltage, 2.0 m^3 · h^-1 of flux of argon, 0.65 m^3 · h^-1 of flux of main hydrogen, 0.4 m^3 ·h^-1 of flux of auxiliary hydrogen and 5.0 × 10^-4 kg · s^-1 of feed rate. Under the same condition, the volumetric concentration of acetylene in carbon-containing gases produced from the mixtures of biomass and waste tires when the mass ratio of biomass and waste tire was 1/2 increased obviously, nearly 2--3 times that of tires or biomass pyrolyzed separately. The concentration of acetylene was closely related to the volatile matter and the amount of oxygen. In addition, the possible mechanism of the pyrolysis occurred under plasma condition was proposed.
