Abstract：In a solar particle reactor,particles play a crucial role as important catalysts and heat storage media.However,their rapid descent leads to a short contact time between the particle catalyst and the reaction gas,and insufficient absorption of solar energy,thereby limiting the reaction rate.Design a particle reactor with asymmetric multi-stage inclined plates and analyze three different baffle arrangement strategies.The results show that this structure can achieve a relatively high outlet particle temperature and hydrogen production rate.When longer stage plates are arranged near the radiation center,the temperature rise of the outlet particles can reach up to 609.85 K,but its comprehensive hydrogen production rate is lower than that of the reactor with longer stage plates far from the radiation center.When the baffle inclination angle is 45°,which is the optimal angle,the overall hydrogen production rate increases from 6.44 to 8.39,an increase of 30.28%.
