摘　　要：研究了影响生物质与废轮胎共热解得到的液体性质及组成的因素。结果表明生物质和废轮胎最大热分解温度均发生在330～360℃，共热解能够产生协同效应。随着加热速率的增大，最大热分解温度逐渐向高温处移动；生物质比例越低热解得到的液体越多；温度越高，得到的液体越少，在350℃下进行共热解得到的液体最多。混合后热解液体的氧含量比生物质单独热解得到液体的氧含量有所降低，芳香族化合物有所增加，并分析了热解液体的族组成。The factors that influence the liquid product obtained from co-pyrolysis of biomass and waste tires and its composition are studied. Results show that the maximum thermal decomposition of biomass and waste tires is both at 330 - 360℃, which can predict a synergistic effect. With the increment of heating rate the maximum temperature of thermal decomposition moves to the higher region; a lower proportion of biomass can bring a higher yield of liquid product; and a higher temperature can bring a smaller yield of liquid product （ maximum yield of liquid can be gotten at a pyrolytic temperature of 350℃ ）. The amount of oxygen is reduced and the aromatic compounds increase comparing to the liquid obtained when single biomass is pyrolyzed. At last the fraction analysis is also made.
