摘要：Proper design of a metal hydride reactor is essential to guarantee the stable high-level reversible hydrogen storage. Multifarious factors, including reactor structure, operating conditions, thermal management measures, and stress relief methods, have been subjected to intensive study. However, less attention was devoted to the effects of motion state for alloy particles on hydrogen absorption heat mass transfer. This paper focuses on the pulverization alloy motion and rearrangement created by a new type of rotating reactor to explain the enhanced heat and mass transfer properties, using real-time dynamic comparative recordings at different rotating speeds. The conclusions indicated that the dynamic rotating reactor showed a higher heat dissipation rate, resulting in lower temperature changes. The hydrogen absorption rate of the rotating reactor was enhanced by 34 % due to the difference in the control weights of the reaction stages and the rate-controlling step. Furthermore, the rotating reactor demonstrated an average hydrogen absorption capacity that was 3.6 % greater than that of a vertical reactor. These advancements owe much to better rearrangement of pulverization alloys caused by a denser frequency and intensity of particle motion and collisions. Under a certain appropriate dynamic range, this new type of rotating reactor can effectively relieve local particle accumulation, further reduce mass transfer resistance, and prominently prevent deactivation in the hydrogen absorption capacity of alloys.
