In order to study the methanol steam reforming performance of the 3D-printed porous support for hydrogen production, three dimensional (3D) printing technology was proposed to fabricate porous stainless steel supports with body-centered cubic structure (BCCS) and face-centered cubic structure (FCCS). Catalyst loading strength of the 3D-printed porous stainless steel supports was studied. Moreover, methanol steam reforming performance of different 3D-printed porous supports for hydrogen production was experimentally investigated by changing reaction parameters. The results show that the 3D-printed porous stainless steel supports with BCCS and FCCS exhibit better catalyst loading strength, and can be used in the microreactor for methanol steam reforming for hydrogen production. Compared with 90 pores per inch (PPI) Fe-based foam support, 3D-printed porous stainless steel supports with FCCS and BCCS show the similar methanol steam reforming performance for hydrogen production in the condition of 6500 mL/(g·h) gas hourly space velocity (GHSV) with 360 °C reaction temperature. This work provides a new idea for the structural design and fabrication of the porous support for methanol steam reforming microreactor for hydrogen production.

为了研究3D打印的多孔氢载体的甲醇蒸汽重整性能以生产氢气，提出了三维（3D）打印技术来制造具有体心立方结构（BCCS）和面心立方结构的多孔不锈钢载体（FCCS）。研究了3D打印的多孔不锈钢载体的催化剂负载强度。此外，通过改变反应参数，通过实验研究了不同3D打印的多孔载体的甲醇蒸汽重整性能，用于制氢。结果表明，带有BCCS和FCCS的3D打印多孔不锈钢载体表现出更好的催化剂负载强度，可用于微反应器中以甲醇蒸汽重整制氢。与每英寸90个孔（PPI）的铁基泡沫支撑相比，3D打印的带有FCCS和BCCS的多孔不锈钢载体在360°C反应温度和6500 mL /（g·h）气体时空速（GHSV）的条件下显示出与制氢相似的甲醇蒸汽重整性能。这项工作为甲醇蒸汽重整微反应器用于制氢的多孔载体的结构设计和制造提供了新思路。
