Efficient methods for preparing mesoporous zeolites towards their catalytic applications
Synthetic zeolites are commercially important materials, primarily used as catalysts in a wide range of chemical industries such as petrochemical processes. Zeolites are crystalline, microporous (500 °C). Diffusion limitation imposed by micropores is one of the major causes of low activity and/or deactivation in zeolites, especially for reactions involving bulky molecules. In industry, mesoporosity can be created in zeolites via ‘top-down’ (i.e. post-synthesis treatments) methods, offering practical yet effective solutions to realise the faster transport phenomena within the mesoporous zeolites and the greater catalytic activity compared to the conventional zeolites. Although they are effective and practical, post-synthetic methods such as steaming and acid/base leaching are energy intensive. In this PhD project, we will built on our recent patented method to explore different strategies of super-fast modification of porosity of various type zeolites (FAU, MOR, MFI, etc.), as well as acidity, for industrial relevant catalysis, e.g. cracking and esterification reactions.
