Abstract
|
Using promoters in different types of catalysts can positively affect the yield of oxidative dehydrogena-tion process and the selectivity of propylene as the main product Titania nanotubes containing distinct promoters including silver, nitrogen and cerium have been synthesized with high specific area by the hydrothermal technique and used as a support in oxidative dehydrogenation of propane. The incipient wetness impregnation method was applied for catalysts preparation Mo/Ce-TNT, Mo/Ag-TNT and Mo/ N-TNT were characterized by various techniques such as XRD, TEM, SEM, EDS, BET, H2-TPR. The presence of these promoters lead to enhanceme nt of propylene yield among which the Mo/Ce- TNT catalyst was of great efficien cy. From the results, it is considered to be quite evident that the oxygen capacity of the cat-alyst containing Ce can contribu te to the oxidation state and redox reactions. In comparison to Mo/TNT, the yield to propylene in the Mo/Ce-TNT sample increased from 9.3% to 14.8% and propylene selectivity substantially surged from 39% to 66.3%.
