Micro Scale Catalyst Activity Facility

FERCo has a bench-scale facility in which we can evaluate the activity of traditional catalyst samples. The test facility currently accepts catalyst samples 1" diameter x 6" long, and is useful for the more traditional determination of catalyst activity. Catalyst activity is determined by measuring NO_x reduction as a function of the NH₃/NO_x ratio. In the bench-scale facility, conditions such as flue gas constituents, humidity, and temperature are closely monitored and controlled.

Traditional activity testing of catalyst samples is useful as a means of assessing catalyst life. However, as the opportunities for obtaining samples are generally limited to the annual planned outages, using laboratory tests to determine catalyst replacement strategies may not be the best solution. Limited activity data will limit the ability to make good decisions. As a solution to this, FERCo has developed the CatalysTraK™ - Activity In Situ Catalyst Activity Test System, in which the Reactor Potential of the SCR can be accurately measured at any time, on-demand, without waiting for an outage to collect a sample.
