采用系统的同步设计程序，实现了一种新的自热反应器的概念，通过甲醇蒸汽重整分散制氢的设计，开发和实施。为了克服实际传热的限制，重整器的概念是按照板式换热器的工作原理设计的。设计过程考虑了数值模拟和实验验证，以及在实际热负荷和机械负荷下反应堆机械稳定性的同步研究。开发重整器概念的主要优化标准是最大的甲醇转化率和最小的CO产量。这种设计顺序允许开发和最终构建能够生产具有10 kW（th）等效热输出的氢气的重整器原型，其在单个装置中集成进料蒸发/过热、蒸汽重整和水煤气变换反应。
The design, development, and implementation of a novel autothermal reactor concept for decentral hydrogen generation by steam reforming of methanol was achieved by employing a systematic simultaneous design procedure. To overcome practical heat-transfer limitations, the reformer concept was designed following the operating principles of a plate heat exchanger. The design procedure considered numerical simulations and experimental verification, as well as simultaneous study of the mechanical stability of the reactor under realistic thermal and mechanical loads. The major optimization criteria for developing the reformer concept were maximum methanol conversion and minimum CO production. This design sequence allowed the development and final construction of a reformer prototype capable of producing hydrogen with an equivalent thermal output of 10 kW(th) that integrates feed evaporation/overheating, steam reforming, and the water-gas shift reaction in a single apparatus.
