本研究采用KOH对中间相炭微球（MCMB）进行化学活化，制备了高中孔含量的活性中间相炭微球（AMCMB）。所得活性中间相炭微球具有发达的孔结构。总孔容最大值为2.45 cm（3）/g，BET比表面积可达3182 m2/g。特别地，所得的介孔活化微珠也具有56.1%至65.7%的中孔含量。从-196 ℃下的N-2等温线可以看出，所得的活性中间相炭微球具有高的吸附容量。(C)2003 Elsevier Science B. V.保留所有权利。
In this study, activated mesocarbon microbeads (AMCMBs) with high mesopore content were prepared from the chemical activation of mesocarbon microbeads (MCMBs) with KOH. The resulting activated mesocarbon microbeads possess well-developed pore structure. The maximum value of the total pore volume is 2.45 cm(3)/g, and BET surface area can reach 3182 m(2)/g. Especially, the resulting mesoporous activated microbeads also have mesopore content ranging from 56.1% to 65.7%. It can be seen from the isotherms of N-2 at -196 degreesC that the resulting activated mesocarbon microbeads have high adsorption capacity. (C) 2003 Elsevier Science B.V. All rights reserved.
