中文摘要：

以高软化点煤沥青和热塑性酚醛树脂为主要原料,机械混合均匀后,采用悬浮法制备沥青/树脂基复合球形活性炭.使用扫描电子显微镜（SEM）、N2物理吸脱附仪、颗粒强度测定仪,对复合球的表面形貌、孔道结构和机械强度进行表征.实验结果表明：树脂的加入不仅能够拓宽球形活性炭的孔径分布,而且能够有效地提高球形活性炭的机械强度.树脂含量为30％的球形活性炭BET表面积为1049 m2/g,总孔容为0.62 cm3/g,平均孔径为8.8nm,同时机械强度达6.2N.通过苯的静态吸脱附测试研究了沥青树脂基球形活性炭的吸附性能,结果表明：复合球形活性炭基本上保持了沥青基球形活性炭的快速吸脱附性能,树脂的加入并没有明显延长复合球形活性炭对苯的吸脱附时间.

英文摘要：

After mechanical mixing, coal tar pitch and thermoplastic phenolic resin were used as the raw mate- rials to prepare spherical activated carbon by suspension method. The surface morphologies, pore parameters and me- chanical strength of the carbon spheres were analyzed by scanning electron microscope （SEM）, N2 physical adsorp- tion-desorption instrument and automatic particle strength tester. Results showed that adding phenolic resin could not only widen the pore size distribution, but also improve the mechanical strength effectively. When the percentage con- tent of thermoplastic phenolic resin was 30%, the mechanical strength of the pitch/resin-based activated carbon reached 6.2 N with specific surface area of 1049 mZ/g, pore volume of 0. 62 cm3/g and average pore size of 8. 8 nm. Additionally, the adsorption/desorption properties of the pitch/resin-based activated carbon were investigated by ben- zene adsorption/desorption test, whose results showed that the introduction of thermoplastic phenolic resin prolonged inconspicuously the adsorption/desorption time and the obtained activated carbon had similar adsorption/desorption properties to the pitch-based spherical activated carbon.
