摘要：

The use of a combination of temperature and space time trajectories with time in order to maintain a constant outlet conversion in spite of catalyst deactivation is shown in the dehydrogenation of benzyl alcohol to benzaldehyde over a copper-silica catalyst. The order of application and the duration of use of each strategy to improve the process were studied, and hence the optimal combinations which allow the highest values of catalyst lifetime and production were found.
