摘要
以究州煤为原料,经脱灰处理后在700℃~1000℃下热裂解制备煤基炭材料.氮气物理吸附和X射线衍射分别考察了炭材料的BET比表面积、孔容以及微晶结构的变化.研究发现随着热处理温度的升高,炭材料的微晶结构变得有序,而BET比表面积、孔容呈现下降趋势.
Carbon materials were prepared by low temperature(700-1 000℃) pyrolyzing Yanzhou coal. BET surface area arid pore volume of the carbon materials were investigated by nitrogen adsorption isotherms. Power X-ray diffraction pattern of carbon materials were studied. The results showed that, with increasing pyrolysis temperature ,carbon materials became structurally order, while BET surface area and pore volume decreased.
