摘要

为了探究不同废轮胎和生物质的共热解转化特性和协同反应机理，实现热解油组分的定向高值化利用，进行了热重分析和固定床热解试验，研究了不同废轮胎和稻壳、秸秆等不同生物质的等质量混合共热解特性，并对热解产物的组成和转化路径进行了比较分析。热重分析结果显示，共热解可有效降低热解反应所需温度，从而减少热解能耗，且小车车胎共热解时的协同作用比大车车胎更加显著。固定床实验结果显示，共热解有助于油中芳香烃向脂肪烃转化、部分含氧类物质向烃类物质转化，但也会促进CO

产生，降低热解气的热值。且共热解炭中的C质量分数明显减小，S也存在从气固相向液相转化的趋势。热解过程中还发现小车轮胎和稻壳灰成分中的大量中性金属氧化物可以促进苯环的羟基化，而大车轮胎和秸秆灰成分中的大量碱性金属氧化物可以促进气化反应。

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.
