Catalyst Study on Liquid-phase Dehydrogenation of Cyclohexanes for Thermo-regenerative Fuel Cell ―Liquid-phase Dehydrogenation of Cyclhexanes by Carbon-Supported Noble Metal Catalysts―

Abstract

Liquid-phase dehydrogenation of cyclohexanes with suspended noble metal catalysts yielded aromatic hydrocarbons and molecular hydrogen exclusively under boiling and refluxing conditions. Retardation effects of aromatic addends, fit well to a Langmuir-type rate equation, were especially large for those which exhibited facile simultaneous hydrogen transfer. The catalysts suitable to the benzene-hydrogenation electrode and to the endothermic dehydrogenation reactor are essentially important in the newly-proposed thermo-regenerative fuel cell system.
