Abstract (en)

[origin: WO2023006380A1] The present invention relates to a method for preparing a microporous material shaped in the form of extruded products, tablets or pellets having a high mechanical strength to prevent crushing and containing at least 90% by weight of KL zeolite (LTL structural type). Said method comprises a step for shaping a KL zeolite with at least one zeolitisable binder and at least one zeolithisation step, in the presence of potassium hydroxide in one and/or the other of the steps in order to obtain a material shaped in the form of extruded products, tablets or pellets containing at least 90% by weight of KL zeolite and having a high mechanical strength to prevent crushing.
