摘要
以地沟油、小桐子油、橡胶籽油及其生物柴油等生物质燃油为研究对象,采用热重分析仪研究了生物质燃油在空气气氛、升温速率为10℃/min下的热重特性,并利用Coats-Redfern积分法进行了生物质燃油燃烧动力学研究.研究结果表明:地沟油热解的初始失重温度和终止失重温度提前,其失重指数P值较高,易于雾化和燃烧;小桐子生物柴油P值更大,热解特性更好;地沟油、小桐子油及橡胶籽油等植物油脂挥发份析出段的化学反应是1.5级反应,燃烧段的化学反应为2级反应,其生物柴油化学反应均是0.5级反应.
The thermogravimetric characteristics of waste oil,jatropha oil,rubber seed oil and their biodiesel are studied in air atmosphere with the heating rate at 10℃ / min by using thermal gravimetric analyzer. The Coats-Redfern integral method is used to study the combustion dynamics of biomass fuels. The research results show that the initial and final weight loss temperature of pyrolysis of the waste oil both advance,and the P value of pyrolysis characteristic parameter is higher,so it is easy to spray and burn; The P value of jatropha biodiesel is larger,and the pyrolysis characteristics of jatropha biodiesel are better. The chemical reaction of volatile component of waste oil,jatropha oil and rubber seed oil is a magnitude of 1. 5,the burning section of chemical reaction being level 2,while the chemical reaction of three kinds of biodiesel are all a magnitude of 0. 5.
