Abstract: The present invention relates to a method for the preparation of a microporous material shaped in the form of extrudates, tablets or beads having good mechanical crush strength and containing at least 90% by weight of KL zeolite (structural type LTL). This method comprises a stage of shaping a KL zeolite with at least one zeolitizable binder and at least one stage of zeolitization, in the presence of potassium hydroxide in one and/or the other of the stages, in order to obtain a material shaped in the form of extrudates, tablets or beads containing at least 90% by weight of KL zeolite and good mechanical crush strength.

Abstract: Process for fixed-bed reforming of a hydrocarbon-based feedstock comprising n-paraffinic, naphthenic and aromatic hydrocarbons, at a temperature of between 400 and 700° C., a pressure of between 0.1 and 4 MPa, and a mass flow of feedstock treated per unit mass of catalyst and per hour of between 0.1 and 10 h−1, by bringing said feedstock into contact with a catalyst comprising platinum, a promoter metal selected from the group consisting of rhenium and iridium, a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, and a porous alumina support in the form of an extrudate characterized by a length “l” of between 1 and 10 mm, a section comprising four lobes, the largest diameter “D” of the cross section of said extrudate being between 1 and 3 mm.

Abstract: The invention relates to a process for preparing an AFX-structure zeolite comprising at least the following steps:
i) mixing, in an aqueous medium, an FAU-structure zeolite having an SiO2 (FAU)/Al2O3 (FAU) molar ratio of between 6.00 and 200, limits included, an organic nitrogenous compound R, at least one source of at least one alkali and/or alkaline-earth metal M, the reaction mixture having the following molar composition: (SiO2 (FAU))/(Al2O3 (FAU)) between 6.00 and 200, H2O/(SiO2 (FAU)) between 1.00 and 100, R/(SiO2(FAU)) between 0.01 and 0.60, M2/nO/(SiO2(FAU)) between 0.005 and 0.45, limits included, until a homogeneous precursor gel is obtained;
ii) hydrothermal treatment of said precursor gel obtained on conclusion of step i) at a temperature of between 120° C. and 220° C., for a time of between 12 hours and 15 days.-
