ABSTRACT:
Trickle-type fixed-bed catalytic reactions are improved, prior to starting or resuming an on-stream period, by purging air from the catalyst bed and reaction zone by downward flow of an inert gas therethrough, flooding the purged reaction zone by flowing a liquid upwardly through the catalyst bed to cover same, then removing the liquid and instituting the on-stream period by introducing gaseous and liquid reactants at the upper end of the catalyst bed to flow downwardly therethrough.
