中文摘要:
      为了给任楼煤矿煤的分级利用提供理论指导,在显微组分分离的基础上,进行了各显微组分热解实验。结果表明:随着 热解温度的升高, 3种显微组分在400~570 ℃均出现明显的失重现象,壳质组在400 ℃左右开始热解,失重速率峰温约为 450 ℃,失重率大;镜质组和惰质组在420 ℃开始热解,失重峰温约为475 ℃。壳质组在整个热解过程中失重率为39%,平均最 大热解速率为0.95 mg/(g·min);镜质组失重率为32.5%,平均最大热解速率为0.53 mg/(g·min);惰质组失重率为29.5%,平均最 大热解速率为0.49 mg/(g·min)。
英文摘要:
      To provide theoretical guidance for grading utilization of coal in Renlou Coal Mine, pyrolysis tests of different maceral have been conducted on the basis of maceral separation. Results show that with increase of pyrolysis temperature, three kinds of macerals at 400-570 ℃ show apparent weightlessness. The exinite group begins pyrolysis around 400 ℃, and weightlessness reaches the largest point when weight loss rate peak temperature reaches about 450 ℃ ; the vitrinite and inertinite groups begin pyrolysis at 420 ℃ and weightlessness peak temperature is about 475 ℃. During the whole pyrolysis process, the weight loss rate of the exinite was 39%, and the average maximum pyrolysis rate was 0.95 mg/(g·min); the weight loss rate of the vitrinite group was 32.5%, and the average maximum pyrolysis rate was 0.53mg /(g·min). The weightlessness rate of inertinite group was 29.5%, and the average maximum pyrolysis rate was 0.49 mg/(g·min).
