摘要：
The hydrodynamics of the platelet millireactor filled with different morphologies of the commercial open cell beta-SiC foams (0.8 < porosity (epsilon) < 0.95 and 890 mu m < cell size (Phi) < 2700 mu m) has been investigated. The axial dispersion profile of an inert tracer in a gas flow (superficial velocity from 0.01 to 0.3 m/s) is estimated by a robust deconvolution procedure The axial Peclet number based on Phi is found to be on the order of 1. The results are in agreement with the literature data and can be compared with the available results for the standard fixed bed.
