The study investigates the properties of industrial-scale supported copper-containing catalysts, H3-11 and MAK-K, in the dehydrogenation of cyclohexanol. These catalysts differ in the mechanism employed for the active component’s immobilization on a silica support: physically bound in the former case and chemically bound in the latter. Within set ranges of temperatures and space velocities (200–250°C, 0.5–2.0 h–1), data were obtained on the conversion rates and selectivity values provided by both catalysts, as well as on corresponding variations in by-product compositions. The trends for both catalysts were found to be similar. The kinetic data were processed using an equation previously suggested for a mixed copper-magnesium catalyst. This equation was confirmed to be able to describe kinetic experiments on the catalysts under study, regardless of the preparation method of a copper-containing catalyst and of the binding mechanism used for the supported active component. Macrokinetic properties were calculated for an industrial-scale reaction mixture and catalyst grain size.
