Resumen o descripción
The present work aims the evaluation of a ruthenium catalyst supported on alumina (Ru/Al2O3) in the reforming of
ethanol for the production of hydrogen. The selection of a suitable synthesis method, support and appropriate
reagents proportions, play a major role in the catalyst performance within this reaction. Catalyst was synthesized by
the incipient impregnation method from a solution of Ruthenium (III) chloride mono-hydrated to get a loading of
10% W, and deposited on α-alumina as support. The catalyst was characterized by: X-ray diffraction (XRD), surface
area (BET), scanning electron microscopy (SEM) and a thermogravimetric analysis (TGA). The evaluation of the
catalyst was carried out using a bench-scale fixed bed reactor system for the reforming of ethanol and reaction
product compositions followed by gas chromatography. Preliminary results indicate that catalyst selectivity was
highly dependent on reaction temperature, steam to ethanol ratio and space velocity for the production of a high
content hydrogen gas product accompanied with low carbon deposition on the catalyst surface
