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。 Pyrolysis of a mixture of lignite and gangue in a coal mine at a 2: 3 ratio. In this experiment, thermogravimetric analysis (TG) and differential scanning calorimetry (DSC) were used. The samples were respectively tested under the same conditions, the atmosphere was nitrogen, the heating rate was 10 ℃ · min -1, 30 ℃ · min -1, 50 ℃ · min -1, 0.055 MPa, the particle size is 80 mesh, 140 mesh and 200 mesh, the reaction termination temperature is 1000 ℃. Through the analysis of test results, the effect of mixing ratio on the pyrolysis of the sample was studied, and the optimal heating rate and particle size were obtained.
