| 摘 要： | 利用兖州烟煤在不同温度下常压流化床氮气气氛的热解半焦作为样品，分析了半焦成分变化的规律，特别是硫的变化规律，并利用热重分析仪分析了不同温度下热解半焦的活化能，研究表明随着热解温度的升高，活化能逐渐降低。热解半焦的研究为煤气化及半焦燃烧的分级转化技术提供了参考。

| Abstract: | The law on component change of carbocoal from different temperature pyrolysis of Yanzhou bituminous coal in ordinary pressure fluidized bed in nitrogen atmosphere is analyzed, especial change law of sulfur, and activation energy of pyrolysis carbocoal in different temperature is analyzed in thermogravimetric analyzer, It is found that activation decreases with pyrolysis temperature increasing. Reference on step conversion of coal gasification and carbocoal combustion is offered by the research on pyrolysis carbocoal. |
