Abstract

The invention deals with a microporous crystalline material, with a characteristic X-ray diffractogram, comprised of oxygen tetrahedra and a metal (T+4 and T+3) with the possibility of introducing surface acidity produced by the substitution in the lattice of some T+4 cations by T+3 cations, which gives rise to a structural charge deficiency that may be compensated by protons, Bronsted acidity, and/or high ratio radium charge cations, Lewis acidity; and the obtaining method thereof, based on the preparation of a gel, its hydrothermal treatment under controlled conditions and the treatment of the resulting laminar material with a solution of an organic compound, a swollen material being obtained, which is subjected to a treatment for the formation of interlaminar pillars of polymeric oxides, obtaining a pillared material that maintains the separation between the sheets, even after calcination.
