用热分析技术测煤低温氧化时的活化能

Measering the Activation Energy of Coal During the Process of Low Temperatune Oxidation by Thernal Analysis Technology

通过对煤样的热解实验,用TG—TGA热分析技术对煤低温氧化过程中的失重率α与dα/dt等数据进行自动采集,利用Coast-Redfern积分法和Achar的微分法相结合,求出煤在低温氧化时的活化能。

Through some pyrogenation experiments on the coal samples, the rate of lostmass a and da/dt during the process of low temperature oxidation of coal is collected automaticly by the TG - TGA thermal analysis technology. The activation energy, using Coast - Redfern integration method and Acharis differentiation method, is figured out.
