摘　　要：选取江蓠、麒麟菜和马尾藻三种海藻为研究对象,进行热解特性研究。在升温速率分别为10℃/min、20℃/min和30℃/min,反应终温为700℃的条件下,分别对热失重曲线和失重速率曲线进行分析,考察升温速率、反应温度等对海藻热解过程的影响,建立海藻热解的反应动力学模型,计算出江蓠、麒麟菜和马尾藻的平均活化能分别为156.1 kJ.mol-1、75.0 kJ.mol-1和119.6 kJ.mol-1。Three kinds of algae, Sargassum, Gracilaria and Eucheuma, were pyrolyzed at the heating rates of 10℃/ min,20℃/min, and 30℃/min from ambient temperature to 700℃ in a thermogravimetrie analyzer to investigate their pyrolytic characteristics. TG and DTG analysis techniques were adopted to study the pyrolysis behavior of algae. The effects of heating rate, time and temperature on pyrolysis process were concluded. The kinetics model of algae pyrolysis were proposed. The value of activation energy of Sargassum ,Gracilaria and Eucheuma were 156.1 kJ · mol ^-1 ,75.0 kJ · mol^-1 and 119.6 kJ · mol^-1.
