| 摘 要： | 用比表面积1183m2/g的活性炭和酚醛树脂分别作为吸附剂和粘结剂,考察了成型工艺对活性炭孔结构及其CO2吸附性能的影响。结果表明,活性炭成型后,比表面积有所下降,但对成型活性炭进行CO2二次物理活化可使其比表面积提高60.7%;粘结剂含量为30wt%、成型压力10MPa条件下所制的成型活性炭在800℃用CO2二次活化2h后,其比表面积、压缩强度和对CO2的平衡吸附量分别为1323m2/g、12.7MPa和0.67mmol/g。

| Abstract: | Monolith activated carbon(MAC) was prepared with phenolic resin as binder,in which the specific surface area of powdery activated carbon was 1183m~2/g.Effect of molding conditions on the pore structure of activated carbon and CO_2 adsorption performance were investigated.Results showed that the specific surface area of MAC was lower than that of activated carbon,but it would increase if the MAC was further physical-activated with CO_2 as activation agent.When the MAC was prepared with 30wt% binder at the mo... |
