The vapor-phase catalytic oxidative dehydrogenation of cyclohexane with COS over SiO<SUB>2</SUB> and Al<SUB>2</SUB>O<SUB>3</SUB> catalysts (e.g., C<SUB>6</SUB>H<SUB>12</SUB>+COS→C<SUB>6</SUB>H<SUB>10</SUB>+CO+H<SUB>2</SUB>S) has been investigated with respect to the production of cyclohexene and cyclohexadiene as well as the mechanism of the dehydrogenation reaction. The representative value of the combined yield of cyclohexene+cyclohexadiene is 8.0% and the combined selectivity to these two products at this yield obtained is 34.0%. These values are comparable to the values 8.0 and 30.8% reported in a recent Japanese patent. The comparison of the catalytic performance between two types of flow fixed-bed reactors demonstrates that the role of solid catalysts is to decompose COS into CO and sulfur, which then dehydrogenates hydrocarbons through a homogeneous mechanism. The results of the kinetic analysis of these reactions, together with the simulation of the overall catalytic reaction system, suggest a contribution of atomic sulfur to the oxidative dehydrogenation of cyclohexane in a conventional flow fixed-bed reactor.
