How to determine catalyst loss in FCC reactor or FCC
Jan 5 2017 11 09 32 AM. The loss of catalyst through reactor or regenerator cyclones is a fairly common problem. Identifying the reason for the loss is often difficult. In this latest blog Tracerco part of Johnson Matthey Plc discusses how a Tru-Scan™ can be a powerful tool for gathering much needed information regarding the loss of catalyst.
