Ru catalysts on carbon fibers were prepared by electroless deposition, with 0.6 wt% Ru loading. The reduced and used catalysts were characterized by different techniques in order to analyze oxidation states and surface composition, the metallic content at volumetric level, and particle size. These solids were evaluated for the production of hydrogen via ethanol steam reforming at different gas hour space velocities (GHSV) at 723 K. Space velocity significantly influenced the distribution of products favoring the formation of acetaldehyde at short contact times while, for longer times, it was possible to obtain a hydrogen rich stream, free of oxygenate compounds.

碳纤维上的Ru催化剂是通过化学沉积法制备的，其中Ru的负载量为0.6 wt％。还原后的催化剂和使用过的催化剂通过不同的技术进行表征，以分析氧化态和表面组成，体积含量的金属含量以及粒径。评估了这些固体在723 K的不同气体小时空速（GHSV）下通过乙醇蒸汽重整制氢的能力。空速显着影响产物的分布，有利于在短接触时间形成乙醛，而在较长的时间内，乙醛的形成有可能获得不含氧化合物的富氢流。
