摘要： 以竹节为原料,采用磷酸法制备醋酸乙烯载体活性炭。实验结果表明,随着温度(325~400 ℃)、浸渍比值(0.60~0.75)和保温时间(3~6 h)的增加,竹节活性炭的比表面积、微孔容积和醋酸吸附量呈先升后降的趋势,而醋酸锌吸附量呈相反趋势;N2吸附等温线表明,竹节活性炭具有发达的微孔和大孔结构。在较优的工艺条件下:活化温度 350 ℃,保温时间 5 h 和浸渍比值0.65,可制得醋酸吸附量 527.5 mg/g,醋酸锌吸附量 70 g/L,比表面积999.0 m2/g和微孔容积 0.468 cm3/g 的活性炭。

Abstract: Bamboo knot was used to prepare activated carbon as vinyl acetate catalyst carrier by phosphoric acid activation.The result showed that the adsorption value of acetate,BET,microporous volume increased with rising temperature (325-400 ℃),impregnate ratio (0.60-0.75) and holding time (3-6 h),but the adsorption of zinc acetate showed the opposite trend.N2-adsorption isotherm showed that the possessed activated carbon developed microporous and macroporous structure.Under the optimized condition,i.e. activation temperature 350 ℃,holding time 5 h and impregnation ratio 0.65, the adsorption value of acetate and zinc acetate,BET,microporous volume were 527.5 mg/g, 70 g/L, 999.0 m2/g and 0.468 cm3/g,respectively.

Key words: activated carbon, bamboo knot, vinyl acetate, carrier
