Abstract

PURPOSE: To regenerate a deactivate Pd catalyst supporting alkali metal carboxylates as promoter (which holds about 50% or more of the initial max. activity value) to a level equal to the initial level in activity and selectivity by treating the deactivated catalyst with steam-contg. gas at a specified temp.
