摘要
在催化和吸附分离等领域,微孔-介孔结构活性炭有广阔的应用前景。以废弃的佛手渣为原料,运用氢氧化钾活化法制备微孔-介孔高比表面积活性炭。考察了炭化和活化等工艺条件对活性炭结构的影响。结果表明,较佳工艺条件下制备的活性炭碘值为1544mg·g-1,BET比表面积1676m2·g-1,微孔BET比表面积350m2·g-1,孔径集中分布在2～5nm之间。
Activated carbon with bimodal micro-meso porous structure will have a great application potential in the fields of catalysis and adsorption-based separation. Activated carbon with high surface area and bimodal micro meso porous structure from bergamot residue was prepared by a potassium hydroxide activation procedure The effects of carbonization as well as activation pa rameters on the structure of the assynthesized samples were investigated in detail. The results showed that at the optimized prepa ration conditions, the synthesized activated carbon had an iodine number of 1544mg·g-1 , a BET surface area of 1676m2·g-1, a microporous surface area of 350m2·g-1 , and a port-size distribution ranging from 2 to 5nm.
