摘要：In this study, a high-efficiency wire mesh hydrogen elimination reactor coated with Pt/Al2O3 via an impregnation-centrifugal coating process was developed to address the safety challenge of hydrogen leakage from storage cylinders. The effects of the coating parameters on the coating loading and adhesive strength were investigated. The hydrogen conversion reached 94.9 % and 99.8 % by the wire mesh reactor at 20 degrees C and 40 degrees C, respectively, which was attributed to the superior heat and mass transfer performance of the wire mesh. The simulation results show that the temperature at the inlet of the wire mesh increases from 20.8 degrees C to 24.3 degrees C as the gas flow rate increases from 30 to 300 ml min-1. This temperature increase plays an important role in hydrogen conversion as a function of the gas flow rate. The wire mesh reactor shows great potential in eliminating hydrogen leakage from the cylinder.
