采用热重法(TGA)研究裂殖壶藻与煤混合的热解特性及混合热解过程的相互影响. 结果表明，煤和微藻的DTG曲线半峰宽分别为225和68℃，挥发分析出的起始温度分别为225和183℃. 可见煤挥发分析出较慢，温度区间较宽. 混合物中随微藻含量增大，挥发分综合特性释放指数逐渐增大，样品热解活性增强. 微藻与煤混合热解过程相互影响程度与样品比例有关. 当煤/藻质量比为1:1时，最大失重速率的计算值与测量值相差0.83%/min，两者在热解过程中存在一定的抑制作用；当煤/藻质量比为3:1和1:3时，两者相互影响不明显. 利用Coats-Redfern法分析热解过程符合一级反应动力学模型.

Pyrolysis process of schizochytrium-coal blends was studied by thermo-gravimetric analysis (TGA) to search the pyrolysis characteristics and interaction in the process of co-pyrolysis. The results showed that the peak width at half height of DTG curves of microalgae and coal were 225 and 68℃ respectively, and the starting temperature of devolatilization were 225 and 183℃ respectively, thus, the devolatilization of coal was slower and occurred over a wider temperature range. With the increase of the content of microalgae in blends, the release index of comprehensive characteristics of volatile D and the activity increased gradually. The interaction between microalgae and coal was related to the proportion of the sample. When the mass ratio of coal to algae was 1:1, the difference between the calculated value and the measured value of the maximum weight loss rate was 0.83%/min, which was inhibited in the process of pyrolysis. When the mass ratio of coal to algae was 3:1 or 1:3, the interaction was not obvious. The pyrolysis kinetics were investigated by Coats-Redfern integral method, and the results showed that the processes could be simplified as a first-order reaction.
