    摘要
  • 摘要: 对新疆后峡煤和滴管炉内的快速热解焦的比表面积、平均孔径、粒径和表面结构进行了分析,研究快速热解过程中原煤的形态变化。将热解焦在热重分析仪上进行气化实验,研究形态变化对气化反应的影响。结果表明,随热解温度的升高,煤焦比表面积与平均孔径变化趋势不同;快速热解过程中煤颗粒除破碎外,还会发生膨胀及凝聚形态变化;不同热解碎片气化趋势不一样,1 200 ℃热解温度下的热解焦气化稳定性最好。
    Abstract: To investigate the morphology change of raw coal during fast pyrolysis and its effect on the coal char gasification reactivity, the specific surface area (SSA), average pore size, particle size distribution and morphology of Xinjiang Houxia coal and the fast pyrolysis coal char from the drop tube furnace were analyzed, and the chars were gasified with TGA (thermogravimetric analyzer). The results show that with the increase of pyrolysis temperature, the change of specific surface area (SSA) and average pore size has different trends. Besides fragmentation, swelling and agglomeration also occur in the fast pyrolysis process. The gasification of fragments is different, and the gasification stability of char under 1 200 ℃ is best.
