Abstract: A method for reducing the level of occluded alkali metal cations from an MSE-framework type molecular sieve comprises either (a) contacting the molecular sieve with a solution containing ammonium ions at a temperature of at least about 50° C. to ammonium-exchange at least part of the occluded potassium ions or (b) contacting the molecular sieve with steam at a temperature of at least about 300° C. and then subjecting the steamed molecular sieve to ammonium exchange.

Abstract: A hydrocarbon feed stream, particularly one comprising heavier hydrocarbons, may be converted to valuable products such as motor gasoline and/or lubricating oil by employing one or more MOF catalysts, which may be prepared from a precursor metal-organic framework (MOF). A MOF catalyst may be prepared by exchanging one or more organic linking ligands of the precursor MOF for an organic linking ligand having a different acidity and/or electron-withdrawing properties, which, in turn, may affect catalytic activity.

Abstract: Methods are provided for performing fluid catalytic cracking (and/or other hydrothermal processing for cracking of hydrocarbons) on a feedstock containing hydrocarbons in the presence of a catalyst that includes zeolite Beta that is stabilized toward hydrothermal conditions. The hydrothermally stabilized zeolite Beta (including any of the various polymorphs) corresponds to zeolite Beta that is formed without the use of an organic structure directing agent, and that is further stabilized by addition of one or more stabilizers, such as lanthanide series elements or phosphorus.

Abstract: The zeolite UTD-1 may be formed under hydrothermal synthesis conditions using a directing agent that does not include a metal atom therein. Methods for synthesizing the zeolite UTD-1 may comprise: combining at least a silicon atom source and a directing agent having a structure of in an aqueous medium; forming the zeolite in the aqueous medium under hydrothermal synthesis conditions, such that the zeolite has a framework silicate with a cationic portion of the directing agent occluded within pores or channels of the framework silicate; and isolating the zeolite from the aqueous medium. The zeolite has a powder x-ray diffraction pattern with at least the following 2θscattering angles: 6.0±0.12, 7.6±0.1, 14.66±0.15, 19.7±0.15, 21.27±0.15, 22.13±0.15, 22.61±0.15, and 24.42±0.10 for a borosilicate form zeolite, or 6.0±0.12, 7.6±0.15, 14.55±0.15, 19.64±0.15, 21.01±0.20, 21.90±0.20, 22.34±0.20, and 24.38±0.20 for an aluminosilicate form zeolite.
