DGB型和超低铬型CO中变催化剂比表面积及孔径分布的测定

Determination of the specific surface area and pore-size distribution of DGB type and ultralow Chromium type HT CO shift catalysts

介绍色谱法测定多孔固体催化剂比表面积及其孔径分布的原理和测定方法。并例举 DGB 型、超低铬型催化剂的比表面积和孔径分布的测定,对其结果进行了分析。

The paper is devoted to introducing the principles and methods of chromatographic determining the specific surface area and pore—size distribution of porous solid catalyst,listing the DGB type and ultralow chromium type shift catalysts as examples,and giving an appraisal to the research results.
