Abstract
ITQ-25 (INSTITUTO DE TECNOLOGÍA QUÍMICA number 25) is a new crystalline microporous material with a framework of tetrahedral atoms connected by atoms capable of bridging the tetrahedral atoms, the tetrahedral atom framework being defined by the interconnections between the tetrahedrally coordinated atoms in its framework. ITQ-25 can be prepared in silicate compositions with a organic structure directing agent. It has a unique X-ray diffraction pattern, which identifies it as a new material. ITQ-25 is stable to calcination in air, absorbs hydrocarbons, and is catalytically active for hydrocarbon conversion.
Claims7
A synthetic crystalline material having a framework of tetrahedral atoms (T) connected by bridging atoms, the tetrahedral atom framework being defined by connecting the nearest tetrahedral (T) atoms in the manner shown in TABLE 1 of the specification.
A synthetic porous crystalline material, as synthesized, characterized by an X-ray diffraction pattern including the most significant lines substantially as set forth in TABLE 2 of the specification.
