AbstractThe 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, Br¦nsted acidity, and/or high ratio radium charge cations, Lewis acidity. The obtention method is 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, preferably a long chain hydrocarbon, that contains a proton acceptor group.; This swollen material is subjected to a specific treatment for the formation of interlaminar pillars of polymeric oxides, obtaining a pillared material that maintains the separation between the sheets, even after calcination.
