New category of zeolites with pentasil ring structure: Catalytic processes on zeolites with controlled distribution of aluminum atoms in the framework

Abstract:
The project is focused on the mapping of the potential of the new category of zeolite catalysts of MFI, FER and BEA structures with controlled ratio of isolated Al atoms and Al pairs in the framework, particularly those with high concentration of isolated Al atoms (up to 90 %) in frameworks of high total Al concentration. The conditions for fulfilling of this task have been obtained by a substantial progress in structural analysis and synthesis of silicon-rich zeolites, which has been achieved recently in our group. The project will provide an important base of knowledge for use of this new category of zeolite catalysts in chemical technology. In accordance with our preliminary results, the project will be focused on zeolites with active protonic and Cu-, Co- and Fe-oxo centers, and catalytic transformation of paraffin izomerization, methanol conversion to olefins, selective catalytic reduction of NOx, decomposition NO/N2O, and oxidation of methane to methanol.
