Abstract
The present invention relates to a zeolite material in the form of FAU zeolite nanocrystal aggregates, to the method for preparing said material, to the zeolite agglomerates prepared from said material with a binder, and to the uses of said material and agglomerate as adsorbents for gas-phase or liquid-phase separation operations, and particularly in methods for separating gas or liquid flows.
Claims17
A zeolite material in the form of FAU zeolite nanocrystal aggregates having at least the following characteristics:
- a Si/Al atomic ratio of between 1 and 1.4, limits inclusive,
- an external surface area of between 20 m2·g−1 and 80 m2·g−1,
- a number-mean diameter of the nanocrystals of between 50 nm and 500 nm, limits inclusive, and
- a number-mean aggregate size of between 0.2 μm and 10 μm.
