摘要
采用氮气吸附法对球形氯化镁载体的孔结构进行了表征,对比分析了自制球形氯化镁载体及国内同类球形氯化镁载体的孔结构参数。结果表明:自制球形氯化镁载体和对比载体均具有中孔孔隙结构,且孔径分布比较均匀;与对比载体相比,自制球形氯化镁载体的总孔容和平均孔径偏大,比表面积相对偏小。
The pore structure of spherical MgC1： support prepared was characterized by nitrogen gas adsorption method, the pore structure paraments of which was compared with same kind support prepared by other research institution in China. The results showed that support prepared by the authors and other institution both contained the mesoporous structure with pore size distribution symmetrical; the total pore volume and the average pore diameter of the authors were greater than that of others, while the specific surface area were small relatively.
