  • Stable small-pore zeolites
    Patent number: 11261097
    Abstract: The present invention provides crystalline aluminosilicate zeolites having a maximum pore size of eight tetrahedral atoms, wherein the zeolite has a total proton content of less than 2 mmol per gram. The zeolite may comprise 0.1 to 10 wt.-% of at least one transition metal, calculated as the respective oxide and based on the total weight of the zeolite. It may furthermore comprise at least one alkali or alkaline earth metal in a concentration of 0 to 2 wt.-%, calculated as the respective metal and based on the total weight of the zeolite. The zeolites may be used for the removal of NOx from automotive combustion exhaust gases.

  • Stable CHA Zeolites
    Publication number: 20210138441
    Abstract: The present invention provides hydrothermally stable crystalline aluminosilicate zeolites with a CHA framework type, wherein the zeolite has a total proton content of less than 2 mmol per gram. The zeolite may comprise 0.1 to 10 wt.-% of at least one transition metal, calculated as the respective oxide and based on the total weight of the zeolite. It may furthermore comprise at least one alkali or alkaline earth metal in a concentration of 0 to 2 wt.-%, calculated as the respective metal and based on the total weight of the zeolite. The invention furthermore provides a one-pot synthesis method for making the alumino-silicate zeolites with a CHA framework type. An aqueous reaction mixture comprising a tetraethylammonium compound, a silica source, at least one alkali or alkaline earth metal hydroxide, a zeolite of the faujasite framework type and Cu-tetraethylenepentamine are mixed, homogenized and heated, and finally, the product is recovered.
