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。

摘要： There is provided a method for preparing a zeolite other than ZSM-5 from a reaction mixture comprising a mixed organic directing agent which is a combination of (a) an organic nitrogen containing compound such as an amine or a quaternary ammonium compound and (b) an alcohol and/or diol. Particular zeolites synthesized by this method include ZSM-22 and ZSM-23. The use of an alcohol or a diol may inhibit the coformation of ZSM-5. Especially when used to prepare ZSM-23, this method enables the preparation of more catalytically active ZSM-23 of reduced crystallite size and also enables the use of lower crystallization temperatures. Particular mixed organic directing agents for the preparation of ZSM-23 are combinations of (a) pyrrolidine and (b) ethanol or ethylene glycol. Other factors which enhance the activity of ZSM-23 include the use of the following in the reaction mixtures for preparing ZSM-23: potassium ions; precipitated silica particles as sources of silica; and spray dried precipitated silica/alumina particles as sources of silica and alumina. The catalytic stability of alumina bound ZSM-23 catalysts is especially enhanced by steaming. Particular reactions which can be catalyzed by ZSM-23 made according to methods described herein include the dealkylation of ethylbenzene and the alkylation of benzene with ethylene.
