Latest Patents

One of David's latest patents is a method for monitoring the performance of process catalysts. This invention discloses 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. The guard bed, which contains guard bed material, is in fluid communication with a catalyst bed that holds a catalyst. At least three monitors are strategically positioned in either the guard bed or the catalyst bed, allowing for the monitoring of at least one parameter. A feed component containing catalyst poisons is supplied to the guard bed or catalyst bed. The feed interacts with the guard bed material or catalyst to eliminate a portion of the catalyst poison, resulting in a product that causes an increase or decrease in the monitored parameter. By comparing these monitored parameters, the method determines the optimal time to replace the guard bed material.
