ABSTRACT:
A process for preparing a hydrocarbon cracking catalyst which consists of preparing a silica hydrosol, adjusting the pH of the sol and at the same time buffering the sol by adding an aluminum sulfate solution, adding clay and zeolitic components, spray drying, washing with water, rare earth exchanging if desired and recovering the product. The catalyst is characterized by excellent attrition resistance and activity.
