| titleOfInvention | Method for determining carbonate content in pseudo-boehmite, method for determining peptized acid using amount and preparation method of catalytic cracking catalyst |
| abstract | The invention relates to the field of catalyst preparation, and discloses a method for determining carbonate content in pseudo-boehmite, a method for determining the peptized acid dosage of the pseudo-boehmite and a preparation method of a catalytic cracking catalyst. The method for determining the using amount of the pseudoboehmite peptization acid comprises the following steps: determining the carbonate content C in the pseudoboehmite Carbonate radical And the dry content w of the pseudoboehmite Dry matter Calculating the amount of peptizing acid according to the method of formula (II): s ═ S Ratio of acid to aluminum +102×C Carbonate radical ÷(w Dry matter × 60 × Z), formula (II), wherein the peptizing acid is used in an amount of S mol, relative to 1mol of pseudo-boehmite in terms of alumina Ratio of acid to aluminum 0.15-0.25; z is 1 or 2. The method for determining the use amount of the pseudo-boehmite peptized acid containing the carbonate is simpler and more accurate, has good repeatability and can stabilize the product quality. |
