To promote the "Basic Hydrogen Strategy" first formulated by Japan [1], hydrogen storage technology based on toluene and methylcyclohexane (MCH) reversible reaction has received widespread attention due to its convenience in hydrogen transport. Superheated vaporization is a necessary process for the catalytic dehydrogenation of MCH, and a novel method with a simple structure to generate superheated water steam quickly and efficiently have been proved in our previous study. However, the start-up response and efficiency of this porous media steam generator has not yet been clarified while using organic fluid. As MCH is toxic to human body, ethanol, which has similar physical properties to MCH, was used in our experiment. Compared to the water, ethanol with lower latent heat has better performance in generating superheated vapor rapidly and efficiently, which also proves that the proposed vapor generator is suitable for the MCH reaction. Considering both heat transfer and fluid flow in the porous media, the energy utilization efficiency and surface temperature were analyzed using one-dimensional models.
