Abstract: A process for the manufacture of large crystal size synthetic porous crystalline molecular sieve requires an aqueous reaction mixture that is organic structure directing agent-free, has a H2O/MOH molar ratio (M is an alkali metal) of 75 or less, a source of X2O3 (X is a trivalent element) and a source of YO2 (Y is a tetravalent element). The source of X2O3 and YO2 is an amorphous material containing both X2O3 and YO2 and having a YO2/X2O3 molar ratio of 15 to 40. The resultant highly crystalline novel materials have crystals with at least one dimension greater than 1 ?m, such as greater than 3 ?m.

Abstract: The present application is directed to a method and system for preparing gaseous utility streams from gaseous process streams, particularly, removing oil contamination from such streams prior to use in a dry gas seal. The methods and systems may include at least one kinetic swing adsorption process including pressure swing adsorption, temperature swing adsorption, calcination, and inert purge processes to treat gaseous streams for use in dry gas seals of rotating equipment such as compressors, turbines and pumps and other utilities. The adsorbent materials used include a high surface area solid structured microporous and mesoporous materials.

Abstract: A process for manufacturing a synthetic porous crystalline molecular sieve requires an aqueous reaction mixture comprising a source of X2O3 (X is a trivalent element), a source of YO2 (Y is a tetravalent element) and a source of MOH (M is an alkali metal). The H2O/MOH molar ratio is within the range of 70 to 126 and the source of X2O3 and YO2 is an amorphous material containing both X2O3 and YO2 and having YO2/X2O3 molar ratio of 15 or less. The molecular sieve products are useful as catalysts and/or absorbents. Such molecular sieves having MFI structure type, TON structure type or the structure type of zeolite beta and a composition involving the molar relationship (n) YO2:X2O3 wherein n is from 2 to less than 15 are novel compositions of matter.
