滴管炉内新疆后峡煤挥发分释放和形态变化
Volatile release and morphologic change of Xinjiang Houxia coal in a drop tube furnace
摘要
Abstract
To investigate the morphology change of raw coal during fast pyrolysis and its effect on the coal chargasification 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..关键词
