摘要
在煤中添加城市污泥,研究它对煤质活性焦吸附性能的影响。实验结果表明:随着城市污泥添加量的增加,活性焦的碘值、比表面积、微孔孔容均先增加后减小。当城市污泥添加量为5%时,活性焦的碘值、比表面积、微孔孔容达到最大。
The effect of adding sewage sludge to coal on the characteristics of resultant activated coke was re- searched. The results showed that the iodine number, surface area and pore volume of the activated coke increased firstly and then decreased with increase of the amount of sewage sludge. When the proportion of sewage sludge was 5%, the io- dine number, surface area and pore volume of the activated coke reached to the top.
