摘要：
The present invention is directed to a phosphorus containing catalyst which is formed by spray drying at a pH preferably less than 3. The present invention also comprises methods for preparing catalysts comprising phosphoric acid treated clay, as well as methods for cracking hydrocarbons utilizing the novel catalysts disclosed herein. The catalysts of the present invention advantageously exhibit low attritability.
