Full-scale autothermal reforming for transport applications: The effect of diesel fuel quality
This study evaluates the feasibility of H-2 production through a fuel flexible reformer, at realistic operating conditions for electricity supply by FC-APUs in the transport sector. The fuel flexibility is evaluated by comparison of autothermal reforming performance with biodiesel (RME), Fischer-Tropsch, low-sulfur diesel (MK1) and European standard diesel (DIN 590). ATR experiments with two monolithic catalysts, Rh1.0Pt1.0Ce10La10/Al2O3 (CAT 1) and Rh1.0Pt1.0Mg4.0Y5.0/CeO2-ZrO2 (CAT 2), sequentially placed in the axial direction of the reformer length were used for full-scale tests. The O-2/C ratio was varied from 0.3 to 0.5 and the H2O/C ratio varied from 2 to 3.5, reaching temperatures in the interval of 700-800 degrees C. The hydrogen production and fuel conversion showed an upward trend from RME < DIN 590 < MK1 < FT with maximum 42 vol.% H-2 and 99% fuel conversion for FT diesel. (C) 2012 Elsevier B. V.
