摘要： A catalytic cracking process for converting a hydrocarbon fraction, preferably boiling in the range of a heavy gas oil, is disclosed in which the cracking catalyst is a large crystal fully crystalline zeolite Beta having a broad range of silica-to-alumina mole ratios, i.e. 20->1000. The zeolite Beta catalyst is synthesized with a nitrogenous organic chelating agent, such as a tertiary alkanolamine, preferably triethanolamine, in the synthesis mixture along with at least one source of organic directing agent such as tetraethylammonium hydroxide, tetraethylammonium bromide and tetraethylammonium fluoride. The zeolite Beta can be used as a stand alone catalyst or an additive catalyst for hydrocarbon cracking reactions along with another molecular seive type catalyst such as a faujasite catalyst or ZSM-5. The large crystal zeolite Beta can also be treated with a source of phosphorus to enhance the properties of the zeolite.

摘要： 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.

摘要： There is provided a catalyst comprising yttrium containing zeolite Y. The zeolite Y is essentially free of rare earth ions. There is also provided a method for making this catalyst. There is further provided a process for using this catalyst for cracking gas oils. It has been discovered that when yttrium is incorporated into this zeolite Y, and when this catalyst is used to crack gas oils, these results improved gasoline selectivity and reduced dry gas make.

摘要： 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.
