摘　　要：近年来,农林废弃物进行资源再利用越来越受到重视,本研究进行了不同生物质发酵残渣及泥煤制备活性炭的比较。组分分析表明,不同生物质发酵残渣及泥煤的组分存在显著差异。在所制备的活性炭中,以糠醛渣为原料、900℃条件下、KOH作为活化剂制得活性炭具有最大比表面积,其值超过2200 m2/g;吸附脱附等温曲线也表明该条件下制备的活性炭具有发达的微孔结构。未分离蛋白玉米秸秆发酵残渣制备活性炭的比表面积随活化温度的升高而升高。In recent years,more and more attention has been paid to the utilization of biomass. The present study used different biomass feedstock fermentation residue and peat for preparation of activated carbon. Component analysis showed that there were significant differences between the different components of the fermentation of biomass residues and peat. The largest specific surface area of activated carbon was obtained using furfural residue as raw material,at 900 ℃,KOH as activator. Under the above conditions,adsorption desorption isotherm curves also showed that the activated carbon produced an extremely well- developed microporous structure. The specific surface area of activated carbon prepared from corn straw fermentation residue increased with the increase of the activation temperature.
