ABSTRACT:
A multi-stage hydrogenation process for hydrogenating a vaporous aldehyde to a corresponding alcohol utilizing a plurality of adiabatic catalytic stages is described. Hydrogenation is allowed to occur substantially completely and adiabatically in each stage. Further vaporous aldehyde or a mixture of hydrogen and vaporous aldehyde is added to the essentially aldehyde-free mixture exiting each catalytic stage prior to entry to the next stage.
