| 摘 要： | 为研究煤与秸秆共气化过程的反应动力学规律,将不同比例的神府烟煤和小麦秸秆掺混并制焦,用热分析法对混合试样的热解协同作用及混合焦CO2气化的反应特性进行了考察,并采用Coats-Redfern方法对该过程进行了动力学解析.研究结果表明:烟煤与秸秆的热解温度相差较大;混合试样呈分段热解,其热解活化能与烟煤热解的活化能相近,秸秆的加入对烟煤的热解没有明显的促进或阻碍作用;焦样的CO2气化反应活性从高到低依次为秸秆焦、混合焦、烟煤焦;秸秆的加入使混合焦的活化能相比烟煤焦有较大降低,促进了混合焦的CO2气化反应的进行.

| Abstract: | To study the kinetics of coal and straw during co-gasification,Shenfu bitumite and wheat straw were blended in different ratios and then pyrolyzed to get blends char.The synergistic effect in the pyrolysis process of blends and the comparison of reactivity in the blends char-CO2 gasification process were investigated by TGA,and the kinetics of both processes was analyzed with Coats-Redfern method.The results show that the pyrolysis temperature of bitumite and wheat straw is different;Co-pyrolysis demonstrat... |
