ZEOLITE WITH A TWO-DIMENSIONAL STRUCTURE, AND USE OF THIS ZEOLITE

摘要

1. A zeolite with two-dimensional structure, having a characteristic nuclear magnetic resonance spectrum, obtained by a process comprising the following stages : a) the treatment of a clay of beidelitte type, in which the silicon atoms have been replaced by aluminium atoms in the tetrahedral layers, in the form of an aqueous suspension, by an aqueous solution containing at least one hydroxide of at least one metal ; b) the removal of the excess hydroxide of the metal which has not reacted on the clay, said removal resulting, after drying the treated clay, in the obtaining of a precursor of the zeolite : c) the heat treatment of the precursor of the zeolite, said treatment resulting in the obtaining of a zeolite with two-dimensional structure ; characterised in that the heat treatment of the precursor has been carried out at a temperature of between 250 and 450 degrees C.
