摘要
为降低汽油吸附用活性炭的生产成本,拓展其原料来源,以大同煤和山东煤为原料,考察了配煤比、炭化及活化工艺参数对汽油吸附用活性炭性能的影响,探究了活性炭孔结构对正丁烷工作容量的影响。结果表明,大同煤与山东煤质量比为9:1时,适宜于制备汽油吸附用活性炭;活性炭烧失率的增加,有利于提高其吸附性能,当烧失率为80%~85%时,其正丁烷工作容量达到11.5 g/100 m L。2 nm^4 nm中孔活性炭有利于对汽油蒸汽的吸附;炭化温度在550℃~650℃范围内,对活性炭性能几乎不影响。
To reduce the production cost of activated carbon for adsorption of gasoline and expand the sources of raw materials, using Datong coal and Shandong coal as raw materials, the effects of blend ratio, carbonization and activation process parameters on performance of activated carbon for adsorption of gasoline were investigated. The influence of pore structure on n-butane working capacity of activated carbon was studied. The results showed that it was suitable for the preparation of activated carbon for adsorption of gasoline when the mass ratio of Datong coal and Shandong coal was 9：1. The increase of activated carbon ignition loss rate was conducive to adsorption improvement. And the n-butane working capacity could reach11.5 g/100 m L when the ignition loss rate was 80%-85%. The mesopore range from 2 nm to 4 nm of activated carbon was conducive to the gasoline vapor adsorption. It had unremarkable effect on the performance of activated carbon when the carbonization temperature was in the range of 550 ℃ to 650 ℃.
