Method of manufacturing fluid catalytic cracking catalyst

摘要

The mfr. of a catalytic cracking catalyst comprises: (a) providing a framework structure having a measurable isoelectric pt., the structure being at least one component selected from a crystalline tetrahedral framework oxide component, an active porous inorganic oxide catalyst framework component and an inert catalytic framework component, (b) providing an inorganic oxide sol having a measurable pH, (c) measuring the isoelectric pt. of each component in the framework structure, (d) measuring the pH of the inorganic oxide sol, (e) matching the isoelectric pt. of each component of the framework structure to the pH of the inorganic oxide sol, (f) combining in soln. the inorganic oxide sol with each component of the framework structure and (g) drying the combined soln.
