| Description
| - Katalytická oxidativní dehydrogenace propanu (ODHP) s použitím N2O na Fe-BEA katalyzátorech byla studována za podmínek kontinuálního procesu a také při periodických změnách složení vstupních složek za podmínek reakčně-regeneračních cyklů. Byl zhodnocen vliv procesních parametrů na tvorbu propylenu, především vliv vstupního poměru N2O/propan a role velikosti zeolitických krystalů. Rozměry zeolitických krystalů ( mikro- nebo nano-částic) se ukázaly jako zásadní parametr pro výtěžek propylenu a selektivitu za vyšších teplot. Zeolity ve formě nano-částic vykazovaly podstatně lepší výsledky v tvorbě propylenu. Časová závislost efektivity procesu ODHP byla vedena s použitím N2O nebo N2O+O2. Reaktivace katalyzátoru oxidačními pulsy ukázala, že kratší pulzy jsou postačující pro regeneraci aktivních center a stabilizaci produkce propylenu. (cs)
- Catalytic oxidative dehydrogenation of propane (ODHP) by N2O over Fe-BEA catalysts has been studied in continuous feed regime against time and with periodic changing of in-let feed composition under reaction-regeneration cycles. The influence of process parameters on the propylene production has been evaluated, namely N2O/propane ratio and crystal size of the parent zeolite. The particle size (micro- vs. nano-particles) of the catalyst has been shown to be a crucial parameter for propylene yield and catalyst selectivity it higher temperatures. The nano-sized catalyst exhibits superior propylene formation in comparison with micro-sezed one. Time dependent performance of ODHP was carried out using reactant streams containing N2O or N2O with O2. eactivation of the catalysts by oxidation pulses revealed that short pulses of oxygen are sufficient to regenerate the active sites and stabilize propylene yield.
