Effect of alumina polymorph on the dehydrogenation activity of supported chromia/alumina catalysts
2020, Journal of CatalysisCitation Excerpt :Earlier Hakuli et. al. observed that the ratio of the intensities of the α-Cr2O3 and γ-Al2O3 peaks in X-ray diffraction patterns had been increased after cycling n-butane dehydrogenation testing of CrOx/γ-Al2O3 catalysts with high Cr-loading [12]. Further, the finding that CrOx – species in CrOx/γ-Al2O3 form the three-dimensional Cr2O3 particles more easily as compared to η-Al2O3-based counterpart is in accordance with the results of the work by Borisevich et.
Effect of CO<inf>2</inf> in the oxidative dehydrogenation reaction of propane over Cr/ZrO<inf>2</inf> catalysts
2018, Applied Catalysis A: GeneralCitation Excerpt :Among them, vanadium-based catalysts, especially highly dispersed VOx species, have shown the best performances in terms of higher propane conversion, and propene selectivity [1,5,6,8,11,16,17]. Nevertheless, other metal oxides such as chromia (CrOx) [18,19] have also been reported to deliver high performance in ODP, which has been ascribed to their high thermal, and mechanical stability, as well as relatively high surface area. Moreover, chromium supported on alumina, silica, or titania is known to be able to catalyze a range of important industrial reactions involving oxidation, polymerization, and hydrogenation-dehydrogenation.
