1 A Study of Structured Packing for Solid Catalyzed Gas-Liquid Reactions Shaibal Roy Muthanna Al-Dahhan Muthanna Al-Dahhan CREL Annual Meeting November 15, 2001 CHEMICAL REACTION ENGINEERING LABORATORY

2 Structures of Interest Monoliths Sandwich Open Cross Flow (Static Mixer) CHEMICAL REACTION ENGINEERING LABORATORY Motivation  Larger volumetric productivity Lower pressure drop  Excellent Mass transfer properties  Higher selectivity (low axial dispersion and shorter diffusion length scales)  Ease of scale-up Structured packing for solid catalyzed gas- liquid reactions provide:

3 Research Goal Implement basket reactor for apparent kinetic studies of  -methyl styrene Develop apparent kinetic model for test reaction at gas and liquid limited regions Know the present state of art Study hydrodynamics (effect of distributor, gas holdup) using CT Develop reactor model equations to predict its overall performance Develop CFD code to study and verify hydrodynamics Develop fundamental understanding of structured packing, verify existing claims and enhance industrial confidence CHEMICAL REACTION ENGINEERING LABORATORY Investigate the structured bed performance using a test reactor
