废轮胎与生物质共热解特性及产物分布研究
Study on characteristics and product distributions of waste tire and biomass co-pyrolysis
摘要
Abstract
In order to explore the co-pyrolysis transformation characteristics and collaborative reaction mechanism of different waste tires and biomass,and realize the directional high-value utilization of pyrolysis oil components,the pyrolysis behaviors were investigated by thermogravimetric analysis and fixed-bed pyrolysis tests.The composition and transformation path of pyrolysis production were compared and analyzed in different kinds of waste tires and rice husks or straw mixture.Thermogravimetry experiment result shows that co-pyrolysis can effectively decrease the temperature required for the pyrolysis reaction,which can reduce the pyrolysis energy consumption.The synergistic effect is more significant when small tires participate in co-pyrolysis than that of Truck and Bus Radial.The results of fixed bed experiment shows that co-pyrolysis can effectively improve the conversion of aromatic hydrocarbons to aliphatic hydrocarbons and the conversion of oxygen-containing substances to hydrocarbon substances.However,co-pyrolysis will lead to the production of carbon dioxide,which will decrease the calorific value of pyrolysis gas.In addition,the mass fraction of C in co-pyrolysis carbon is significantly decreased,and the S also has a tendency to transform from gas-solid phase to liquid phase.It is also found that large amounts of neutral metal oxides in Passenger Car Radia and rice husk ash can promote the hydroxylation of benzene rings,while large amounts of alkaline metal oxides in Truck and Bus Radial and straw ash can promote the gasification reaction.关键词
