    • A process for producing zeolite aggregates involves providing a formable paste composed of zeolite, a binder composed of an organic/metal oxide containing aluminum, a peptizing agent and water; forming the paste into an aggregate, preferably by extruding into an extrudate; curing the aggregate; hydro-thermally calcining the aggregate; and washing the hydro-thermally calcined aggregate with a washing medium, preferably followed by rinsing with a rinsing medium to remove residual washing medium from the aggregate. The washed and rinsed aggregate may then be permitted to equilibrate or is subjected to a drying procedure. Preferably, the washed and rinsed aggregate is again subjected to curing/hydro-thermal calcining. The resultant aggregates, such as extrudates, have an exterior surface with openings and interstitial spaces between particles of binder and zeolite which communicate by such openings between the exterior surface of the aggregate and micropores of the zeolite; the aggregates also exhibit characteristics of crush strength greater than about 0.9 pounds per millimeter and a loss by attrition of less than about 3.0%. Regenerable catalysts, such as reforming catalysts, based on such aggregate also exhibit a catalyst activity pass through to the zeolite bound in the aggregate of at least 70% of the initial catalyst activity of freshly prepared zeolite, as well as exhibiting more than about 70% of the reforming benzene yield that the reforming catalyst exhibited when similarly tested prior to being exposed to a hydrocarbon stream under specified reforming conditions of the catalyst activity test procedures.
    • 一种生产沸石聚集体的方法包括提供由沸石组成的可成形糊料,由含铝的有机/金属氧化物,胶溶剂和水组成的粘合剂; 将所述糊料形成为聚集体,优选通过挤出成型为挤出物; 固化骨料; 水热煅烧骨料; 并用洗涤介质洗涤加热热煅烧的聚集体,优选随后用冲洗介质冲洗以从聚集体中除去残余的洗涤介质。 然后可以洗涤和漂洗的骨料平衡或进行干燥过程。 优选地,洗涤和漂洗的骨料再次进行固化/水热煅烧。 所得到的聚集体,例如挤出物,具有在粘合剂和沸石颗粒之间具有开口和间隙的外表面,该孔与沸石的外表面和沸石的微孔之间的这种开口连通; 聚集体还具有大于约0.9磅/毫米的压碎强度的特征,并且损耗小于约3.0%。 基于这种骨料的可再生催化剂,如重整催化剂,也表现出催化剂活性通过沸石结合的沸石,其为新制备的沸石的初始催化剂活性的至少70%,并显示大于约70% 的重整苯产率,当在催化剂活性测试程序的特定重整条件下暴露于烃流之前,类似地测试重整催化剂显示。
