Patent number: 5160500Abstract: 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.Type: GrantFiled: October 30, 1991Date of Patent: November 3, 1992Assignee: Mobil Oil CorporationInventors: Pochen Chu, Donald J.

Patent number: 5053374Abstract: 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.Type: GrantFiled: November 2, 1989Date of Patent: October 1, 1991Assignee: Mobil Oil CorporationInventors: Robert P. L. Absil, Philip J. Angevine, Joseph A. Herbst, Donald J. Klocke, John P. McWilliams, Scott Han, David S. Shihabi
