Simulation Study in the Reactor of Hydrogen Compressor Based on Metal Hydride
With fast economic development and increase of energy consumption, reasonable use of waste heat, especially low quality heat of large quantity, has been one of the key points in increasing utilization ratio of energy. Hydrogen compressor(single stage static compressor) based on metal hydride play an important role in power recycle, including low grade heat. Being a core of hydrogen compressor based on metal hydride, reactor is used as an integrated unit of reaction and heat transfer. The simulation study in the reactor of hydrogen compressor covers a lot of factors such as alloys type, heat and mass transfer rate, particle size and shape, porosity, crystal form and effective thermal conductivity. This paper deals with the temperature change and distribution, reaction rate change and distribution in single stage static hydrogen compressor during both adsorption and desorption. According to the energy balance model, exergy balance model, kinetics model and principle hypotheses, the simulation results show that the desorption rate was obviously faster than absorption rate, and the temperature difference during adsorption was nearly 12 while the temperature difference during desorption was about 35 . It also ℃ ℃ indicates that further study is of essential significance for both research and industrial application.
