摘要：采用热天平研究生物质半焦CO2气化反应动力学特性。考察半焦粒径、热解制焦温度以及热解制焦气氛对气化反应碳转化率的影响。采用随机孔模型、未反应芯缩核模型和混合模型对生物质半焦气化反应速率随碳转化率变化的趋势进行拟合,并求出半焦气化的动力学参数,结果表明随机孔模型的拟合效果最好。
The kinetics characteristics of biomass semi-char gasification with CO2 were studied with TGA. The main influence factors of gasification kinetics of semi-char and C02, such as biomass semi-chat particle size, pyrolysis temperature and pyrolysis atmosphere were researched. The gasification reaction rate as a function of the conversion degree of carbon was analyzed by random pore model, unreacted core shrinking model and integrated model. The dynamic parameters of semi-char gasification were obtained. The random pore model shows advantage in fitting the experiment data compared with other two models.
