ABSTRACT:
This invention is to a method of manufacturing fluid catalytic cracking catalyst. In particular, the invention is to a method of manufacturing a catalytic cracking catalyst which incorporates a step of matching the isoelectric point of each component of the catalyst framework structure to the pH of an inorganic oxide sol used to form the matrix component of the catalyst. The resulting catalyst product has a controlled pore size and is extremely durable.
