| 摘 要： | 利用AS-703比表面积、孔径分布测定仪对几种回收丙酮溶剂的商品活性炭进行了比较深入的剖析,从微观结构上阐明了影响丙酮回收用活性炭的主要因素,并提供了国产化样品,与进口商品活性炭相比较具有价格低吸附性能好等优点.微孔容积的大小决定了丙酮吸附量的多少,而与总孔容积关系不大.丙酮回收用活性炭的孔径主要集中在1nm左右,微孔容积在0.40～0.50cm3/g.

| Abstract: | Serial commercial activated carbon for acetone recovery was inspected by surface area and pore distribution analysis instrument(AS-703).It illuminated the main factors influencing acetone recovery from the aspect of microstructure.Domestic sample of activated carbon with similar adsorption capability and lower price comparing with imported commercial activated carbons was provided.The pore suitable for the adsorption of acetone is micropore.The size of micropore volume determines the adsorption capacity of acetone,without relating to total pore volume.Micropore volume of the activated carbon is in the range of 0.40～0.50cm3/g and mean pore radius is 1nm. |
