Abstract: The invention concerns a microporous crystalline material, with a characteristic X-ray diffractogram, made up by oxygen tetrahedra and one metal (T+4 and T+3) with the possibility of introducing surface acidity produced by the substitution in the network of some T+4 cations (normally Si+4) by T+3 cations (normally Al+3), which gives rise to a structural charge deficiency which can be offset by protons, Brönsted acidity, and/or cations with a high charge-radium ratio, Lewis acidity. The method of preparation is based on the modification of the laminar structure of a mixed oxide (normally SiO2, Al2O3) synthesized from a gel treated under controlled hydrothermal conditions, intercalating organic molecules with a proton-acceptor group and a long hydrocarbonic chain between its laminae. The intercalated material has laminae with a significant separation between them due to the presence between them of the organic chains.
