Abstract
Disclosed is a method for determining when to replace a guard bed material used to remove one or more catalyst poisons from a feed based on a parameter change in a process. A guard bed having a guard bed material is in fluid communication with a catalyst bed having a catalyst. At least three monitors are positioned in said guard bed or said catalyst bed and at least one parameter of the guard bed or catalyst bed is monitored. A feed component comprising one or more catalyst poisons is supplied to said guard bed or said catalyst bed. The feed is contacted with said guard bed material or said catalyst to remove at least a portion of a catalyst poison and to form a product which produces an increase or a decrease in said parameter. The monitored parameters are compared to determine when to replace the guard bed material.
