AbstractThe isothermal gasification tests of rice straw char and wood chip char were carried out under CO2 atmosphere,using the thermo-gravimetric analyzer(TGA) over the temperature range of 800~950 ℃. The gasification reactivity of two chars increased with the i
Other Abstract利用热重分析仪在800-950℃对稻秆焦和木屑焦CO2等温气化过程进行了研究。分别采用等转化率法和随机孔模型求解了稻秆焦和木屑焦气化反应的动力学参数。通过等转化率法发现,随着碳转化率的增加,反应活化能随着碳转化率的升高而增大,稻秆焦和木屑焦在碳转化率为0.02时刻(即接近初始时刻)的活化能分别为157.2 k J/mol和166.4 k J/mol;采用随机孔模型计算得到稻秆焦和木屑焦的活化能分别为155.1 k J/mol和165.5 k J/mol,与等转化率法求得的碳转化率为0.02时刻的活化能接近
