ABSTRACT:
This invention relates to the catalyst composition resulting from the addition of phosphorus, and optionally, a matrix material, to a porous crystalline material having the structure of MCM-22, along with the method for making the catalyst composition, and the method for using the catalyst composition in catalytic cracking. It is desirable to improve the hydrothermal stability of the catalysts which are based upon porous crystalline materials having the X-ray structure of MCM-22 to increase the activity that the catalyst maintains after repeated cycles of steaming such as is experienced in the FCC process. It has been found that phosphorus addition to a porous crystalline material having the structure of MCM-22 improves the hydrothermal stability of the resulting catalyst. This improved catalyst is useful in organic conversion processes, e.g., catalytic cracking processes.
