Provider: Grantová agentura ČR
Programme: Postdoktorské projekty (řešení od 1.1.2012)
Implementation period: 01.01.12 - 31.12.14

Description:
Project is focused on the study of catalytic activity isomorphously substituted [Fe]-zeolites of following types: MFI, MEL, IFR in the direct ammoxidation of propane. Their catalytic activity together with their physico-chemical properties will be studied in the function of the conditions and type of pretreatment (calcination, steaming in the water vapor, nitridation and reductive nitridation), structure of the material and concentration of iron. Special attention will be devoted to the process of the nitridation of Fe-zeolites, to the mechanism of this process and the impact of the conditions of the nitridation on the catalytic properties of the material. Project should help to understand the in uence of the changes in the acid-base and redox properties of the material and its activity in the ammoxidation of propane and also to identify the structure of the active centers of the catalyst. Results from this research could help to de ne the new active and selective catalytic system for the direct ammoxidation of propane.
