title = "Partial oxidehydrogenation of cyclohexane to cyclohexene over nickel supported catalysts modified by rare-earth metal oxides",
abstract = "Partial oxidehydrogenation (ODH) of cyclohexane to produce cyclohexene selectively was studied over NiO/γ-Al2O3-doped-Ce, -La, -Gd, -Dy catalysts. Doping of catalyst with rare-earth metal oxides showed significant effect. Compared with NiO/γ-Al2O3, the Ce-, Dy - and Gd modified catalysts were more active and efficient in selective production of cyclohexene by ODH of cyclohexane. At about 5\% conversion, the selectivities of catalysts towards cyclohexene increased in the order Ni10LaAl < NiAl < Ni10GdAl < Ni10CeAl < Ni10DyAl. Modification of γ-Al2O3 supported nickel oxide with Ce, Gd, Dy inhibited the formation of bulk nickel aluminate and led to higher nickel content as compared to unmodified carrier. This is an abstract of a paper presented at the 19th Annual Saudi-Japan Symposium on Catalysts in Petroleum Refining and Petrochemicals (Dhahran, Saudi Arabia 11/8-9/2009).",
