Abstract
The present disclosure is directed to producing zeolite structures with GME topologies using organic structure directing agents (OSDAs) comprising a piperidinium cation, and the compositions and structures resulting from these methods. In some embodiments, the crystalline products have a molar ratio of a molar ratio of Si:Al that is greater than 3.5.
Claims16
A crystalline microporous aluminosilicate composition of GME topology comprising:
- (a) an oxide of silicon, and optionally an oxide of germanium;
- (b) an oxide of aluminum, and optionally one or more oxides of boron, gallium, hafnium, tin, titanium, indium, vanadium, or zirconium, having a molar ratio of Si:Al in a range of from 4.4 to 5 and which crystalline microporous aluminosilicate composition of GME topology exhibits a powder XRD pattern having at least five peaks having 2-theta values at 7.5±0.1°, 11.6±0.1°, 14.9±0.1°, 17.9±0.2°, 19.9±0.1°, 21.75±0.15°, 28.1±0.2°, or 30.1±0.1°.
