    摘要: A process is provided for converting feedstock hydrocarbon compounds over a catalyst composition which comprises clay and a zeolite component, at least one of which has been treated with a phosphorus-containing compound, for example, ammonium dihydrogen phosphate or phosphoric acid, and which is spray dried at a low pH, preferably lower than about 3. An embodiment of the present invention comprises an improved catalytic cracking process to produce high octane gasoline and increased lower olefins, especially propylene and butylene.

    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: New catalyst compositions of superior hydrothermal stability, which evidence increased gasoline plus distillate yields, improved coke selectivity and reduced C.sub.4.sup.- gas yields, are based on framework dealuminated faujasitic zeolites having a framework silica to alumina molar ratio of from about 5 to 100. In a preferred embodiment, an "ultrastable Y" composited with a matrix, is subjected to a treatment with a source of aluminum and rare earth compounds followed by hydrothermal treatments to improve the hydrothermal stability and selectivity of the catalyst for catalytic cracking. This is evidenced by higher gasoline plus distillate yields and lower coke and gas production at lower catalyst useage per barrel of feed relative to commercial cracking catalysts currently being used.
