Latest Patents

Dougnier's latest patents focus on the process for the synthesis of zeolites having an aluminosilicate composition. One of his key innovations involves preparing an aluminosilicate gel that contains a structuring agent ST. This gel is then subjected to crystallization to form a zeolite precursor. The resulting zeolite, which contains the structuring agent ST in its cavities and channels, is produced through the calcination of the precursor. The structuring agent ST is derived from polyalkylene oxides, which have specific chemical properties that enhance the zeolite's performance. The zeolites produced exhibit a Si:Al ratio greater than 1, potentially exceeding 3, and possess cubic symmetry. These zeolites can be utilized as adsorbents or catalyst components, either directly or after cation exchange.
