(118e) Simulation of Novel Micro Reactor with Porous Catalytic Surface for Simultaneous Separation

The performance of conventional contact process equipment is consistently observed to deviate from the theoretical predictions and operates less efficiently on either with capacity or with yield. The reltaionhsips developed especially for multiphase flows in bulk systems do not predict the basic process parameters such as contact surface, residence time. The micro reactors are qualified with well defined flow structure, contact surface giving way to achieve high perfomance efficiency. The present study is aimed at simulating micro channel reactors made of porous walls. The reactor wall surface is considered as catalytically active surface for separation of product. The reaction is first order decomposition and takes place in the liquid phase. The simulations are carried out for different patterns of gas-liquid flows in the micro-channels and compared the performance. The flow patterns can be achieved by controlling the swithcing gas/liquid flows suitably. The standard numerical techniques have been used for solving conservation equations. The performance of the system is evaluated based on total conversion and energy input. The high performance is due to achievement of well dispersion of gas phase into liquid phase, and high catalytic surface area per unit volume.
