Prevention of Activated Carbon Bed Ignition and Degradation during the Recovery of Cyclohexanone

[摘要] References(10)Cited-By(1)Oxidation of cyclohexanone adsorbed on activated carbon was investigated in relation to solvent recovery. It became clear that the respective reactions through which 1,2-cyclohexanedione and adipic acid formed were largely responsible for carbon bed ignition and carbon degradation. Results were explained assuming that the former reaction is of pseduo-first-order and proceeds much faster than the latter. Further, it was concluded that the concentration of carbonyl group on the carbon surface and that of oxygen in the gas phase affected both reactions strongly.
