Abstract:
A method for recovering chloro-species from a process for reducing a metal-containing catalyst, said method comprising:(a) passing a reduction inlet stream comprising a reducing agent to a reduction zone containing said catalyst containing said metal and chloride, reducing at least a portion of said metal on said catalyst and removing at least a portion of the chloride from said catalyst in said reduction zone at reduction conditions, and withdrawing from said reduction zone a reduction outlet stream comprising said chloro-species; and(b) passing at least a first portion of said reduction outlet stream to a sorption zone containing said catalyst, sorbing at least a portion of said chloro-species on said catalyst in said sorption zone at sorption conditions, and withdrawing from said sorption zone a sorption outlet stream having a decreased concentration of said chloro-species relative to said reduction outlet stream.
