Abstract
A process for preparing a hydrocarbon cracking catalyst is disclosed. The process consists of preparing a silica sol by passing sodium silicate through an ion exchange resin column to form a silica sol containing about 5% silica. Clay and zeolitic components are added and the product is spray dried. This process is advantageous in that it produces a more dense and hence more attrition resistant catalyst.
