Abstract
A process for automatically providing for periodic surge flow or liquid slugs in the catalyst bed to insure that the catalyst is periodically fully wetted. Therefore, before dry spots develop in the bed and some catalyst particles are deprived of the liquid reactants, the aforesaid liquid pulse or slug will rewet the catalyst. This desired periodic introduction of a liquid slug through a catalyst bed is accomplished by the provision of a plurality of automatically actuating and operating siphon means disposed and distributed across the area of the distributor tray means within the reactor.
