A process is disclosed for producing small crystal, high surface area crystalline materials having the MFI and/or MEL framework-type, designated as EMM-30, using as a structure directing agent tetrabutylammonium cations and/or tetrabutylphosphonium cations, or 1,5-bis(N-tributylammonium)pentane dications, and/or 1,6-bis(N-tributylammonium)hexane dications. The compositions made according to that process, as well as the various dication compositions themselves, are also disclosed.

Provided here are zirconium-substituted hierarchical zeolite compositions and methods of preparing such catalytic compositions. One such method involves subjecting the zirconium-substituted zeolite to a framework modification process using a single template to produce a framework-modified zeolite, followed by subjecting the framework-modified zeolite to an ion exchange process to produce a hierarchical zeolite composition. Also provided are methods of catalytic cracking of hydrocarbon feedstocks using these zirconium-substituted hierarchical zeolite compositions.

The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

The present invention provides for a process for the production of an aluminosilicate zeolite from fly ash, and in particular but not exclusively, to a process for producing a high silica content zeolite from fly ash without the addition of an external silica source, such as sodium silicate.

Disclosed is a method for readily and inexpensively producing zeolite without using an organic structure-directing agent (organic SDA). Specifically disclosed is a method whereby a gel containing a silica source, an alumina source, an alkaline source and water is reacted with zeolite seed crystals, to produce a zeolite with the same kind of skeletal structure as the zeolite. The gel used is a gel of a composition whereby, when a zeolite is synthesized from this gel only, the synthesized zeolite comprises at least one of the kinds of composite building units of the target zeolite.
