发表刊物：Energy

摘要：The hydrogenation process usually accompanies with strong thermal effect, which may lead to the poor
hydriding performance if the reaction heat cannot be removed promptly. The design and optimization of
metal hydride reactor can significantly advance heat & mass transfer and H2 storage efficiency. A novel
radiation mini-channel reactor (RMCR) was proposed to improve the thermal efficiency, and a radiation
mini-channel reactor with jacket (RMCR-J) was developed to eliminate the unfavorable heat transfer
regions inside RMCR. The 7 reactors were extensively investigated and compared by 3D COMSOL models,
revealing that radiation tube behaved the best reaction performance. The structural parameters of RMCR
& RMCR-J were optimized as spread branch number of 3, main tube radius of 2 mm, branch tube radius
of 2 mm, axial pitch of 5 mm, mounting distance of 8.5mm and tilt angle of 0
. Moreover, the operation
conditions were simulated and the optimal performance could be achieved at H2 pressure of 1 MPa and
initial fluid temperature of 293 K. The sensitivity analysis results indicated that axial pitch and mounting
distance was the most sensitive structure factor for RMCR and RMCR-J, respectively. In addition, RMCR-J
was confirmed to present a superior performance than RMCR.
