Abstract:

This invention relates to the synthesis of large pore composite molecular sieves and to the synthetic large pore composite molecular sieves so produced. The molecular sieves of the invention have the same general utilities of the comparable molecular sieves of the prior art but have been found to be superior catalysts and absorbents. This invention relates to a hydrothermal synthesis of large pore molecular sieves from nutrients, at least one of which contains an amorphous framework-structure, and which framework-structure is essentially retained in the synthetic molecular sieve. This invention stems from a discovery that the intrinsic porosity characteristics of a nutrient that possesses an amorphous cation oxide-framework can be substantially retained in the final molecular sieve containing product formed by a hydrothermal process by carefully controlling the conditions under which the hydrothermal process is conducted. For example, the invention contemplates retention of the particle size in a final molecular sieve-containing product that corresponds with that of an amorphous cation oxide-framework nutrient used in its manufacture. This invention drives the selection of process conditions to achieve one or more of macro and meso porosity (âlarge pore composite porosityâ) in the final molecular sieve product as a direct product of the hydrothermal reaction producing the molecular sieve.

International Classification:

US Classification:

422180, 422171, 422177, 422222

Abstract:

An apparatus for converting at least one nitrogen oxide, such as NO, NO , or N O converts oxide in the presence of a catalyst supported on a metal mesh-like structure. The mesh-like structure is preferably fibrous formed of metal or ceramic fibers which may include knitted wire, sintered metal fibers and so on and has a porosity greater than about 85%. The mesh is formed into channels, preferably corrugations, and includes vortex generators, which generate turbulence to create a pressure differential across the mesh, to promote flow of fluids through the mesh pores which normally do not exhibit flow therethrough in the absence of such pressure differential. Preferred embodiments of structured packing and monoliths are disclosed each having a catalyst preferably in the mesh pores and/or coated on the fibers for converting the nitrogen oxide. In one embodiment, corrugated mesh-like sheets are arranged in series with a ceramic solid monolith structure with the corrugated sheets initially receiving the fluid with the at least one nitrogen oxide to be converted and which fluid then flows into the monolith structure to complete the conversion. In other embodiments, the mesh-like structure may have different configurations including a honeycomb arrangement and may include metal, metal and ceramic or ceramic and may be fibrous.
