Driven by the international trend and national strategy of distributed hydrogen energy applications, the hydrogen that is in situ produced and consumed through online methanol steam reforming is very attractive. The membrane reactor technology can realize efficient one-step hydrogen production and purification, and it can significantly improve the flux per unit equipment volume and technical-economics. This project aims at the inherent problem of poor heat transfer performance of conventional particle-packed membrane reactors, which significantly hinders the heat supply and catalytic performance of the endothermic reaction, thereby limiting the scale-up of membrane reactor and hydrogen flux of single membrane reactor module. We propose a new conceptual design—Highly Conductive Foam Structured Membrane Reactor, and conduct systematic study from two levels: “structured catalyst element” and “novel membrane reactor equipment”. Based on the scientific principle of matching the solid-solid interface wettability, we will study the solid-solid interfacial mechanism of efficient construction of foam structured catalysts in depth, in order to achieve high strength loading and controllable construction of the catalyst coating so that it can adapt to the application scenarios of high-speed gas impact and high-frequency hot and cold shock. We investigate the effects of the structural configuration, operating conditions of the novel membrane reactor, the geometrical structure and thermal conductivity of the foam structural elements on the performance of novel membrane reactor; explore the key criteria and critical dimensions for the flexible and reliable scale-up of the novel membrane reactor. The final objective is to build modular, novel membrane reactor technology for distributed hydrogen production which is applicable to both hydrogen stations and hydrogen vehicles.
