Abstract: Methods are provided for synthesizing ZSM-58 crystals with an improved morphology and/or an improved size distribution. By controlling the conditions during synthesis of the ZSM-58 crystals, crystals of a useful size with a narrow size distribution can be generated. Additionally, by controlling the ratio of water content to silica content in the synthesis mixture, it has unexpectedly been found that ZSM-58 crystals can be formed with an improved morphology. The improved morphology can result in ZSM-58 crystals with a more uniform size across the various dimensions of the crystal, which allows for more uniform diffusion within the crystal. This is in contrast to conventionally synthesized crystals, where the size of the crystal can vary along different axes of the crystals.

Abstract: In a process for producing a metal containing catalyst composition suitable for effecting hydrocarbon hydrogenation and/or dehydrogenation reactions, a catalyst support comprising a porous crystalline material combined with an amorphous binder is treated with an anchoring material capable of bonding to the surface of the support and to a metal component. In addition, a precursor to the metal component is deposited on the surface of the catalyst support and then the treated catalyst support having the precursor deposited thereon is subjected to conditions effective to convert the precursor to the metal component and to cause the anchoring material to bond to the surface of the support and to the metal component.
