| Abstract: | A new method for quantitatively measuring the surface acid amount of solid catalyst was set up on a self-made pulse chromatographic adsorbent reactor. The surface acid amount of the catalysts with different content of HZSM-5 zeolite as well as the distribution of the acid was measured by pulse chromatography method with pyridine as adsorbate and cyclohexanone as internal standard in the presence of anhydrous ethanol solvent. The experimental results reveal that the new method is very convenient and applicable, and the quantitative result for the solid catalysts is reliable. |
