摘　　要：采用混捏的方法,以活性碳为原料制备了氧化铝-活性炭载体,并通过傅立叶红外光谱、X射线衍射及N_2吸附对复合载体的酸性和表面物相进行表征。结果表明,复合载体的酸性高于单纯的氧化铝载体和活性炭载体,粘结剂用量越多载体机械强度越强,但是孔径和比表面积越小,其XRD图谱中杂质峰越多。A Alumina - Carbon （AC ） Supported was synthesized by kneading method using activated carbon as raw material, and crystallinity were investigated using fourier transform infrared spectroscopy, X - ray diffraction and N 2 adsorption. The results showed that the acidity of AC more than a single activated carbon support and alumina support, the more adhesive, the mechanical strength of the AC support more strong, however,the smaller the pore size and surface area,there are much impurity on the AC surface by XRD patterns of support.
