摘要：Renewable energy accommodation entails extensive use of modular devices, whose performance degrades remarkably from the lab scale to the industrial scale. This work presents a multi-objective design optimization approach for modular devices scale-up as exemplified by hierarchical numbering-up of reverse water-gas shift microreactors. The optimization objectives cover a wide span of competing system performance metrics, including the reaction performance, energy efficiency, space occupation, environmental impact, and costs. The decision variables involve the hierarchical geometry, branching, and inter-stack connection schemes of the microreactor stacks. The obtained Pareto-optimal designs suggest that multiple short stacks with small intra-stack distribution channels and large inter-stack connection tubes can well balance cost and performance. Meanwhile, single-stack structures with large distribution channels are more suitable for portable applications. The methodology not only can be extended to the numbering-up of various types of microreactors but also has essential guidance for the integration design of other modular devices.
