  • Patent number: 7947252
    Abstract: The invention relates to a microporous crystalline material which is characterised in that it has the following chemical composition in the calcined state: X2O3:n YO2:m GeO2, wherein (n+m) is equal to at least 5, X is a trivalent element, Y corresponds to one or more tetravalent elements other than Ge and the Y/Ge ratio is greater than 1. Moreover, in the synthesised form without calcination, said material has an X-ray diffraction pattern in which the main lines thereof are as follows: (1), in which (mf) represents relative intensity of between 80 and 100, “d” represents relative intensity of between 20 and 40 and “md” represents relative intensity of between 0 and 20, which is calculated as a percentage with respect to the most intense peak. The invention also relates to the method of preparing said material and the use thereof in the conversion of food products comprising organic compounds.
