Factors affecting the MTW zeolite cristallization process
- Universita della Calabria, Rende (Italy)
The synthesis mechanism of the high silica zeolite types other than MFI is rarely studied in the open literature. This work is devoted to the role of different parameters governing the zeolite MTW crystallization process. The influence of the most important factors: the nature of the silica and alumina source, the type of the organic cation, the alkalinity of the reaction mixture and the crystallization temperature, was studied. The molar composition of the initial hydrogel was varied in other to determine the crystallization field of the zeolite MTW. The observed morphology and particle size of the crystallites are related to the corresponding reaction conditions. The competitive formation of the other zeolite types (prevalently MFI and BEA) is discussed.
