  • Hydrothermal conversion of Y-zeolite using alkaline earth cations
    Patent number: 6436364
    Abstract: Hydrothermal synthesis of the natural, alkaline earth zeolites via the alteration of Y-zeolite is presented. Synthetic versions of the zeolites harmotome, heulandite, brewsterite and gmelinite are synthesized from Y-zeolite using alkaline earth cations containing solutions. The effect of the composition of the starting zeolite, the composition of the solution phase, the presence or absence of seeds and the experimental conditions are discussed.

  • Process for producing hydrodesulfurization catalyst and hydrodesulfurizing gas oil therewith
    Patent number: 6063265
    Abstract: A process for producing a hydrodesulfurization catalyst is disclosed, comprising impregnating an inorganic oxide carrier containing a crystalline aluminosilicate with a solution consisting of Group VI metal oxide, a Group VIII metal oxide, and phosphorus. Also disclosed is a process for deep hydrodesulfurization of a gas oil fraction using said catalyst to obtain gas oil having an extremely low sulfur content.
