    Abstract: The present invention is directed to a novel catalyst useful in the cracking of hydrocarbons. The catalyst of the present invention is formed with at least one zeolite, a first clay having a first average particle size and a second clay having a smaller average particle size than the first clay, wherein at least one of the clays or the zeolite is first treated with a source of phosphorus, such as phosphoric acid. These components are mixed in a slurry and spray dried at a low pH. Thus the present invention is also directed to a process for preparing a zeolite catalyst. The catalysts of the present invention advantageously do not require calcination in order to obtain low attritability.
