摘要
在CARLO -ERBA 180 0自动吸附仪上使用N2 吸附法分析了以太西无烟煤为原料 ,用几种不同工艺生产的煤基活性炭的孔隙结构。用BET方程处理N2 等温吸附数据 ,测得活性炭的BET表面积和孔体积 ,计算出活性炭的平均孔半径 ,研究了活性炭的孔径分布情况 ,用丁烷工作容量 (BWC)来分析评价活性炭的吸附———脱附性能 。
Coal based activated carbon was made by different production process and Taixi anthracite as raw material. The pore structure of this coal-based activated carbon is analysis by N 2 adsorption method on CARLO-ERBA 1800 automatic apparatus. The N 2 isothermal adsorption data are treated by BET equation to obtain BET surface area and pore volume of activated carbon and to calculate the average pore radius. The pore diameter distribution of activated carbon is studied. Adsorption and desorption property of activated carbon were analyzed and evaluated by BWC. The result is shown that, the best adsorption and desorption property of activated carbon is made by catalytic activation process.
