WebFeb 22, 2016 · If the fluid flow is up through the catalyst bed then the bed can become fluidized if the pressure drop is high enough to support the weight of the catalyst. Fluidized beds usually have a lower pressure drop than down flow at high flow rates (Towler, 2012). In addition, fluidizing the catalyst eases the transition from one reaction zone to another. WebTo enhance the Low Cycle Length of NHT Reactor due to High DP across Catalyst Bed. Sep 2024 - Feb 2024.
