Abstract

An improved procedure for purging volatile material from a conversion catalyst in which the catalyst is contacted with a flowing gaseous medium to extract the volatile material, characterized in that the improvements include: (a) increasing the pressure applied to the catalyst to a previously determined higher value, while maintaining a continuous flow of gaseous medium, and (b) lowering the pressure, when it reaches the previously determined high value, to a lower value, thereby extracting the volatile material from the catalyst at a higher speed .
