Abstract:
The present invention describes a method to increase the activity of a catalyst by first performing an ion exchange step with a potassium ion, followed by performing an ion-exchange step with an ammonium ion. Specifically, the present invention describes a method to increase the acidity of a zeolite by incorporating a potassium salt ion-exchange prior to an ammonium salt ion-exchange step. Even more specifically, the present invention is drawn to a method of increasing the activity of a zeolite by employing more than one potassium ion exchanges followed by at least one ammonium ion exchange. The present invention also describes a method to reduce the amount of sodium normally found in commercially produced zeolite by employing any of these methods. The present invention is also drawn to the catalysts produced by any of these methods.

The invention relates to the use of particulate silicone resins in the absence of added organic solvents with particulate inorganic materials to form structured bodies and in particular molecular sieve containing structured bodies. The silicone resin is used in the form of a particulate with an average particle size of less than 700 um. Upon calcining, the silicone resin is converted to silica which acts as a binder.

US Classification:
208113, 502 66, 502 64, 502232, 502240, 502243
Abstract:
In a method of forming a shaped body, a mixture is formed comprising a particulate silica-rich material, water and a potassium base or basic salt, wherein the total solids content of the mixture is from about 20 to about 90 weight percent. The mixture is extruded into extrudates and the extrudates are dried and heated to a temperature of from about 300 C. to about 800 C. to form the shaped body.

US Classification:
423702, 423700
Abstract:
In a process for synthesizing a crystalline molecular sieve, an aqueous synthesis mixture is produced capable of forming the crystalline molecular sieve. Crystallization of the synthesis mixture is induced so as to form crystals of said molecular sieve in the synthesis mixture and, when crystallization is complete, the molecular sieve crystals are allowed or caused to separate from the remainder of the synthesis mixture to produce a solid phase comprising said molecular sieve crystals and a supernatant liquid phase. The supernatant liquid phase is then decanted from the solid phase to recover the molecular sieve crystals and the crystals are dried without initially being subjected to washing or filtration.

Abstract:
This invention relates to a process for isomerizing paraffins comprising the step of contacting a feed containing paraffins with a catalyst comprising a synthetic porous crystalline material, designated MCM-68, which exhibits a distinctive X-ray diffraction pattern and has a unique crystal structure which contains at least one channel system, in which each channel is defined by a 12-membered ring of tetrahedrally coordinated atoms, and at least two further, independent channel systems, in each of which each channel is defined by a 10-membered ring of tetrahedrally coordinated atoms, wherein the number of unique 10-membered ring channels is twice the number of 12-membered ring channels.
