Kinetics for oxidative dehydrogenation of n ‐butanol over copper‐barium catalyst was investigated in a fixed‐bed reactor. The effects of oxygen addition, temperature, initial partial pressure, and time factor on the conversion were studied. The results show that the catalyst is quite active and selective for the dehydrogenation of n ‐butanol and will become more active when a small amount of oxygen is added in the feed stream. A partial redox model including a pair of redox reaction steps parallel with a direct dehydrogenation reaction step was developed. The rate constants for the three reaction steps were evaluated. The model can predict the experimental data quite well, with a standard deviation less than ±5%.
