Abstract: Hydrogen represents a promising fuel since it is considered as a dean energy carrier and also because during its combustion only water is emitted. It can be produced from different kinds of renewable feedstocks, such as ethanol. In this sense, hydrogen could be treated as biofuel. Three chemical reactions can be used to achieve this purpose: steam reforming (SR), partial oxidation (PDX), and autothermal reforming (ATR). In this study, the catalysts implemented in steam reforming of ethanol were reviewed. A wide variety of elements can be used as catalysts for this reaction, such as base metals (Ni; Cu and Co) or noble metals (Rh, Pt and Ru), usually deposited on a support material that increases surface area and improves catalytic function. The use of Rh, Ni and Pt supported or promoted with CeO2, and/or La2O3 shows excellent performance in ethanol SR catalytic process. The ratio of water to ethanol, reaction temperatures, catalysts loadings, selectivity and activity are also discussed, as they are extremely important for high hydrogen yields.
