Title:
METHOD FOR PREPARING MICROPOROUS MATERIAL
Document Type and Number:
WIPO Patent Application WO/2003/006375
Kind Code:
A1
Abstract:
A method for preparing a microporous material which comprises a mixing step of forming an alkaline mixed fluid of inorganic materials comprising at least one crystallization adjusting agent selected from an ammonium ion, a phosphonium ion and an amine, a silicon dioxide component, and a noble metal component and allowing fine particles to precipitate in the mixed fluid, a solid−liquid separation step of separating the fine particles from the mixed fluid, and a crystallization step of heating the solid component obtained by the solid−liquid separation, to thereby crystallize it&semi and a method for preparing a microporous material which comprises a mixing step of forming an alkaline mixed fluid of inorganic materials comprising at least one crystallization adjusting agent selected from an ammonium ion, a phosphonium ion and an amine and a silicon dioxide component and allowing fine particles to precipitate in the mixed fluid, a solid−liquid separation step of separating the fine particles from the mixed fluid, and a crystallization step of adding a noble metal component to the solid component obtained by the solid−liquid separation and heating the resulting mixture, to thereby crystallize it.
