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： Low acidity refractory oxide-bound zeolite catalysts, for example, silica-bound ultrastable Y zeolite, possessing physical properties, e.g., crush strength, similar to those of their alumina-bound counterparts are described. Since low acidity refractory oxide-bound catalysts are inherently less active than alumina-bound zeolite catalysts, the former are particularly useful in hydrocarbon conversion processes in which reduced coke make increases catalyst cycle length. Due to their stability in acid environments, the low acidity refractory oxide-bound zeolite extrudate herein can be acid treated without unduly compromising its structural integrity.
摘要翻译： 描述了具有类似于其氧化铝结合的对应物的物理性能，例如粉碎强度的低酸度难熔氧化物结合的沸石催化剂，例如二氧化硅结合的超稳定Y沸石。 由于低酸度难熔氧化物结合的催化剂固有地比氧化铝结合的沸石催化剂具有更低的活性，因此前者在烃转化方法中特别有用，其中减少的焦炭使催化剂循环长度增加。 由于其在酸性环境中的稳定性，本文中低酸度难熔氧化物结合的沸石挤出物可以进行酸处理，而不会不利地损害其结构完整性。
