Sažetak
Soot can be largely generated as a toxic pollutant, during the air-lean operating of high-temperature incineration of solid waste, including biomass and plastic waste. The main objective of this study is to demonstrate the synergistic effect of biomass and plastic waste co-pyrolysis on soot formation at high temperatures (1100-1250 °C). The effect of temperature, biomass type, and co-pyrolysis ratio on the yield, morphology, composition, and reactivity of soot particles are studied. Results show that the measured soot yield as well as the particle size during co-pyrolysis is smaller than expected. This synergistic effect degree increases with the increase of biomass ratio (0~50 wt.%) and the decrease of pyrolysis temperature. Wood co-pyrolysis presents a stronger synergistic effect on soot yields than straw co-pyrolysis. The synergistic effect on the reactivity of soot oxidation depends on biomass ratio. At 10 wt.% straw co- pyrolysis ratio, the measured soot oxidation reactivity is lower than theoretical one ; while the straw co-pyrolysis ratio increase to 50 wt.%, the measured one is much higher than theoretical one because of the catalysis from potassium chlorine. By comparison, because the potassium in wood ash is much lower than that in straw ash, the synergistic effect of wood co-pyrolysis on soot oxidation reactivity is weak.
