Abstract: The invention provides methods and compositions for precursors and for the synthesis of zeolites. The invention makes use of intimately homogeneous precursors which avoid the formation of a difficult to work with gel stage in zeolite formation. This allows for the synthesis of zeolite in a much shorter period of time and with much lower amounts of structure directing agents.

Abstract: Disclosed are novel aqueous aluminum complex compositions and methods of making and using them. The novel compositions comprise very low halide content, even when made from aluminum chlorohydrate. The compositions find use in the production of zeolites, coatings, abrasives, binders, and refractories; and in the treatment of wastewater for example. The methods of making the novel compositions include passing a first aqueous aluminum complex composition through an anion exchange column or otherwise contacting the first composition with the anion exchange resin to provide a second aqueous aluminum complex composition that is different from the first aqueous aluminum complex composition. Also disclosed are methods of making zeolites and aqueous silica-alumina compositions from the novel aqueous aluminum complex compositions.

Abstract: Described herein are methods and compositions for zeolite synthesis. The methods and compositions involve modifying a colloidal silica sol with a metal compound and in the presence of a structure directing agent, followed by heating to form a zeolite. The methods and compositions result in rapid zeolite formation, even at reduced concentrations of structure directing agent.

Abstract: The invention provides a method of increasing the absorbency of an absorbent article. The method includes introducing a super-absorbent polymer composition to a paper web in a papermaking process to increase the absorbent capacity of an absorbent article made in the process. The polymer composition includes a super-absorbent polymer and a cross-linking agent applied to the paper web. The paper web is then subjected to heat in a heated drum or a through-air drier to cure or cross-link the super-absorbent polymer.
