    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： A catalytic cracking catalyst and process are disclosed using a catalyst containing: a matrix, a large pore molecular sieve, a shape selective paraffin cracking/isomerization zeolite and a shape selective aliphatic aromatization zeolite. An exemplary catalyst comprises dealuminized zeolite Y, optionally containing rare earth elements, HZSM-5, and gallium ZSM-5 in a matrix. The matrix contains and protects the relatively fragile zeolite components and acts as a sodium and metals sink. The large pore molecular sieve cracks large hydrocarbons to lighter paraffins and olefins. The shape selective paraffin cracking/isomerization component cracks/isomerizes the paraffins produced by the large pore molecular seive. The shape selective aliphatic aromatization catalyst converts light paraffins and olefins into aromatics. A single shape selective zeolite, e.g., ZSM-5 with a controlled amount of an aromatization component such as gallium, may promote both paraffin cracking/isomerization and aromatization.

    摘要： A multistage process for reducing NO.sub.x in flue gas from fluid catalytic cracking catalyst regeneration. Flue gas is preferably removed after each stage. NO.sub.x formed in each regeneration stage is converted to N.sub.2 prior to discharge from a stage by operating at least the downstream ends of each regeneration stage at oxygen-lean conditions. Staged regeneration can be achieved by passing spent catalyst through a transport reactor in plug type flow and sequentially contacting the catalyst with a plurality of oxygen-containing streams.
