Abstract: Current process simulation platform is not able to simulate effectively the chemical looping process for hydrogen production,which restricts seriously the optimization to the design of reactor size and process.Based on axial diffusion model,a dual fluidized bed reactor chemical looping hydrogen production process is established,and the reactor structure and operating parameters are optimized,which provides theoretical guidance for the chemical looping hydrogen production process.The established axial diffusion model for a fluidized bed reactor can simulate the reforming process between natural gas and metal oxides in an industrial scale reactor.The optimization results show that the chemical looping hydrogen production process can produce hydrogen at a high efficiency,with a hydrogen/methane production ratio reaching 232% and an average production cost of around RMB 11 000 per ton of hydrogen.
