摘要

mesoporous and microporous aluminosilicates with high catalytic activity in acid catalysis reactions and their preparation process.; This invention relates to novel materials of microporous and mesoporous aluminosilicate having a chemical composition expressed by the following formula (in moles of oxides): AI_ {2} O_ {3}: mSiO_ {2}: nM_ {2} O wherein the value of m is between 2 and 50, preferably between 4 and 10; M represents the cations Na ^ {+} or {H ^ +}, and the value of n is between 0.01 and 2, preferably between 0.1 and 1.; These materials have a regular distribution of pores whose average diameter is between 1.0 nm and 15 nm. also they have a high catalytic activity in acid catalysis reactions. their preparation process and their use as catalysts of hydrocarbon conversion reactions, such as cracking, isomerisation, transalkylation, alkylation, dimerization and polymerization is described.
