摘要
对沙尔湖矿区的 3 个煤样与准东矿区的准东煤、宜化煤、红沙泉煤 6 种煤样在 400℃、600℃、800℃、1 000℃进行快速热解反应,并对热解气体进行气相色谱分析、焦油产物进行GC-MS分析,探究温度对 6 种煤样热解产物特性的影响.结果表明:沙尔湖矿区 3 个煤样在 4 个温度段中的气体产物组分更丰富,在 600℃下热解产生的煤焦油成分中,酚类含量最高、烯烃含量最低;准东煤、宜化煤的热解焦油中以烷烃为主;此外,沙尔湖矿区 3 个煤样与红沙泉煤的热解产物特性类似.
Abstract
Three coal samples from Shaerhu area and six coal samples from Zhundong area,including Zhundong coal,Yihua coal and Hongshaquan coal,were used to conduct rapid pyrolysis reactions at 400℃,600℃,800℃and 1 000℃.The pyrolysis gas was analyzed by gas chromatography and tar products were analyzed by GC-MS to explore the influence of temperature on the pyrolysis products of the six coal samples.The results showed that the gas products of the three coal samples from Shaerhu area had richer components under four temperatures,and the phenol content was the highest and the olefin content was the lowest among the coal tar components generated by pyrolysis at 600℃.The pyrolysis products of Zhundong coal and Yihua coal were mainly alkanes.In addition,the pyrolysis products of three coal samples from Shaerhu area had similar characteristics to those of Hongshaquan coal.
