Liquid-Solid Mass Transfer Coefficient in High Pressure Trickle Bed Reactors
The Effect of High Pressure on the Liquid-Solid Mass Transfer Coefficient (Kls) in a Trickle Bed Reactor Was Investigated for the First Time using the Electrochemical Method. It Was Found that Kls Increases Noticeably at High Pressure and High Gas Flow Rate. as Superficial Liquid Mass Velocity Increases, Kls Increases for All Pressures and Superficial Gas Velocities Studied. the Effects of Reactor Pressure and Gas Flow Rate on Kls Follow the Trend Proposed by Al-Dahhan and Dudukovic1.2 based on Five Limited Cases. the Current Correlations, Which Were Developed based on Atmospheric Data, Failed to Predict the Kls Values Measured in This Work as Well as the Trend of the Reactor Pressure Effects.
