摘要
运用扫描电镜实验对不同温度下表面活性剂处理后的气煤颗粒表面进行观测,通过表面活性剂种类与温度两个参数,分析煤颗粒表面裂-孔隙结构发育特征。结果表明:较高温度条件与复合型表面活性剂处理后煤颗粒表面裂-孔隙结构发育程度较高。
The surface of gas-coal particles treated with surfactants at different temperatures was observed by scanning electron microscope(SEM).The development characteristics of surface crack-pore structure of coal particles were analyzed by two parameters of surfactant type and temperature.The results show that the development of surface crack-pore structure of coal particles is higher after treatment with higher temperature and compound surfactant.
