In this contribution, a theoretical study of ethanol steam reforming (ESR) over a Pd-based catalyst in a plate microreactor is carried out. ESR is convectively heated by means of a flue gas stream flowing through contiguous plates in a cross-flow configuration.

To describe the performance of the reactor under steady-state adiabatic operation a pseudo homogeneous 2D model is considered. The influence of the main operating variables and the different flue gas feed arrangements on the performance of the reformer has been analysed with the aim of accomplishing a total hydrogen production of 1 kW_th.

The results show that the cross-flow plate reactor is a promising design to carry out the ESR under operating and design conditions that favour thermal homogeneity (high heat transfer) and a high enough residence time of the reactants in the reforming side.

在此贡献中，对板式微反应器中基于Pd的催化剂进行乙醇蒸汽重整（ESR）进行了理论研究。通过流经连续板的烟气流以对流方式对流加热ESR。

为了描述反应器在稳态绝热运行下的性能，考虑了伪均质2D模型。分析了主要的操作变量和不同的烟气进料方式对重整器性能的影响，目的是实现总氢气产生1 kW _th。

结果表明，错流板反应器是一种有前景的设计，可以在有利于热均质性（高传热）和反应物在重整侧停留足够长的时间的设计条件下进行ESR。
