褐煤和煤矸石混合热解研究

The Pyrolysis Study of Lignite(coal) and Coal Gangue

对某煤矿的褐煤和某煤矿煤矸石的混合物按2:3的比例进行热解。本实验采用热重分析法(TG)和差示扫描量热法(DSC)。将试样分别在同一条件下进行试验,气氛为氮气,升温速率分别为10℃·min^(-1)、30℃·min^(-1)、50℃·min^(-1),压力为0.055 MPa,粒度分别是80目、140目和200目,反应终止温度为1000℃。通过对试验结果分析,研究分析混合比对试样热解的影响,并得到最佳升温速率和粒度。

Experiment about the pyrolysis of the lignite(coal) and coal gangue's mixture in a same proportion(2:3) in different coal mine,and the experimental method is thermogravimetry(TG)and differential scanning calorimetry(DSC).Put the sample in the same conditions for the test,atmosphere for N_2,heating rate is 10℃·min^(-1),30℃·min^(-1) and 50℃·min^(-1),pressure is 0.055 MPa,granularity is 80 accounts,120 accounts and 200 accounts,response to terminate the temperature is1000℃.By analysising the test results,further study is to sample the different effects of the rate and granularity,and fond out the optimum.
