Pinning in Radial Flow Moving Bed Reactor

For certain types of chemical reactors where the catalyst decays rapidly but reversibly, continuous operation is possible by use of a Radial Flow Moving Bed Reactor (RFMBR). A Continuous Catalyst Regeneration (CCR) reformer unit is one of the industrial units using the RFMBR. RFMBR can be simply...
