Abstract
The influence of alkali metal (Na, K, Cs) doping on the surface and catalytic properties of γ-Al2O3 supported nickel oxide in the selective oxidehydrogenation of cyclohexane was investigated. Among the organic products quantified were cyclohexene, 1,3-cyclohexadiene, benzene, and CO, CO2, and H2O as inorganic products, respectively. Cyclohexene selectivities of up to 75% were achieved. Doping of the catalyst with alkali was found to have no promoting effect. Selectivity to cyclohexene increased in the following order: NiO/Cs-Al2O3 < NiO/K-Al2O3 < NiO/Na-Al2O3 < NiO/Al2O3.
