PARTIAL CATALYTICAL PROPANE OXIDATION ON ALUMOSILICATE CATALYSTS
نویسندگان
چکیده
In the scientific literature problem of obtaining highly selective aluminosilicate catalysts is related to study influence nature active centers (acidity their surface) on catalytic activity. some cases a linear dependency can be observed between rate acidity and catalytical The alumosilicates, in its turn, considerably dependent mode preparation. case preparing alumosilicates by joint precipitation with increase Al2O3 from 0.1 1.0% concentration acid increases proportion aluminum oxide contents. With further increased more slowly whereas at 75% decreased. this work physical chemical properties five alumosilicate different content aluminium them are synthesized analyzed. reaction propane oxidation air oxygen was investigated define alumosilicates’ process. all specimens products were as follows: formaldehyde, acetic acid, CO, CO2, C3H6, H2, H2O, well aldehyde found small amount. At high (above 770 K) temperature CH4 C2H4 found. possibility formaldehyde selectivity demonstrated. catalysts’ activity under accounts for surface. A suggestion made about formation catalyst. On basis research relevant scheme proposed.

Partial oxidation of ethanol on vanadia catalysts on supporting oxides with different redox properties compared to propane
The influence of the support material of vanadia catalysts on the reaction rate, activation energies, and defect formation enthalpies was investigated for the oxidative dehydrogenation of ethanol and propane. Characterization by infrared absorption–reflection spectroscopy (IRAS), Raman and UV–vis spectroscopy verifies a high dispersion of vanadia for powder and thin-film model catalysts. The su...
متن کاملRole of water in the partial oxidation of propane to acrylic acid over Mo1V0.3Te0.23Nb0.12Ox catalyst
Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...

متن کاملSynthesis of single-site copper catalysts for methane partial oxidation.
Cu-Exchanged zeolites are known as active materials for methane oxidation to methanol. However, understanding of the formation of Cu active species during synthesis, dehydration and activation is fragmented and rudimentary. We show here how a synthesis protocol guided by insight in the ion exchange elementary steps leads to highly uniform Cu species in mordenite (MOR).
