Description

technical field

[0001] The present invention relates to a process for the direct preparation of SSZ-13 zeolites containing copper atoms. This new approach requires a specific combination of copper polyamine complexes with additional organic molecules that act as organic structure-directing agents (OSDAs). The present invention also includes using the Cu-SSZ-13 material synthesized according to the method of the present invention as NO x A method of selective catalytic reduction (SCR) catalysts. Background technique

[0002] Zeolites are composed of TO interconnected by oxygen atoms 4 Microporous materials composed of tetrahedrons (T=Si, Al, P, Ti, Ge, Sn...), which generate pores and cavities of uniform size and shape (in the molecular scale range Inside).

[0003] Barrer described the first synthetic zeolites in 1948. [Barrer, J. Chem. Soc. 127 (1948)]. Since this discovery, more than 200 new zeolite structures have been discovered, all of which contain different por...
