MICROPOROUS AMORPHOUS MATERIAL, PREPARATION METHOD THEREOF AND USE OF SAME IN THE CATALYTIC CONVERSION OF ORGANIC COMPOUNDS

摘要

The invention relates to a microporous amorphous material which is characterised in that it has a chemical composition in the calcined and anhydrous state which can be represented by empirical formula x (M1/nXO2): y YO2: SiO2, wherein: x has a value of less than 0.2 and can be equal to zero; y has a value of less than 0.2 and can be equal to zero; M is selected from among H<+>, one or more inorganic cations having a +n charge and a mixture of same; X is one or more chemical elements in oxidation state +3; and Y is one or more elements in oxidation state +4. The inventive material is also characterised in that it has a uniform pore distribution, a micropore volume of greater than or equal to 0.05 cm<3>.g<-1 >and a specific surface area of greater than 100 m<2>.g<-1>. The invention also relates to the preparation method thereof and use of same.
