The kinetics of ethanol oxidation to acetaldehyde in gaseous phase was investigated over Cu-Mn-Fe oxide catalyst. A step-wise reduction-oxidation mechanism was suggested according to the results of ethanol oxidation over given catalyst in the absence of oxygen. It was found that both CH3CHO and H2O acted as inhibitors to the reaction and the former was stronger than the latter in this respect. The inhibiting effect of CH3CHO could be elucidated in terms of the competitive adsorption of CH3CHO with EtOH on the...

The kinetics of ethanol oxidation to acetaldehyde in gaseous phase was investigated over Cu-Mn-Fe oxide catalyst. A step-wise reduction-oxidation mechanism was suggested according to the results of ethanol oxidation over given catalyst in the absence of oxygen. It was found that both CH3CHO and H2O acted as inhibitors to the reaction and the former was stronger than the latter in this respect. The inhibiting effect of CH3CHO could be elucidated in terms of the competitive adsorption of CH3CHO with EtOH on the oxidative sites of the catalyst surface.The reaction data were collected using a gradientless recycle reactor in the temperature range of 135 - 190℃ and partial pressure range of PE= (0.1-0.3) ×10-2 atm of ethanol and PO2= (0.5-8) ×10-2 atm of oxygen. A steady state three-stage redox model was deduced to explain the experimental results. The rate equation (1) (see p.126) thus derived gave a satisfactory representation of the rate data of ethanol oxidation. The rate constants of the two redox steps k1, k2 and the equilibrium constant of CH3CHO adsorption K were calculated by the method of least squares multiple linear regression. The deviation between the calculated values of the reaction rate and the experimental results was 6.69%. The activation energies of reduction and reoxidation of the catalyst were 12.53 and 17.47 Kcal/mol respectively, and the adsorption heat of CH3CHO was -9.21 Kcal/mol. A simplified two-stage redox model gave also a good fit to experimental data at lower partial pressure of CH3CHO.
