ntrinsic kinetics of ethyl acetate hydrogenolysis to ethanol over a Cu-Zn/Al2O3 catalyst
With the aim of exploring an alternative ethanolproduction technology to the traditional cereal fermentation process, intrinsic kinetic studies of the hydrogenation of ethyl acetate(EA) to ethanol(EtOH) over a Cu-Zn/Al2O3 catalyst have been conducted in a tubular isothermal integral reactor under the following conditions: t=180-230℃, p=1.0-1.5MPa, LHSV of EA 0.7-1.9g/(g·h) and n(H2)∶n(EA)=20-50. The Runge-Kutta-Felhberg (4,5) algorithm was chosen as the numerical integration method, and the kinetic model parameters were estimated by means of the Levenberg-Marquardt method. Statistical tests and residual distribution results showed that the derived powerlaw kinetic model is acceptable and reliable for the catalytic hydrogenolysis of ethyl acetate to ethanol.
