Hydrogen production from ethanol for PEM fuel cells. An integrated fuel processor comprising ethanol steam reforming and preferential oxidation of CO

Influence of structural parameters on the reaction of low temperature ethanol steam reforming over Pt/Al2O3 catalysts

“…The use of bioethanol as renewable hydrogen carrier is attractive due to its wide availability, storage and handling safety, and because it can be produced from several biomass sources. Reformation of ethanol with steam produces high yields of hydrogen at elevated temperatures, whereas, recently, alternative processes operating at lower temperatures are being investigated [2][3][4][5][6][7][8][9][10][11][12][13][14]. Such processes could offer significant energy efficiency advantages.…”

Elimination of acetaldehyde from hydrogen rich streams employing Ni/ZrO2

“…Lima et al [2], in order to eliminate CO in the presence of acetaldehyde, employed the preferential CO oxidation reaction (PROX) using Pt/CeO 2 as catalyst. Due to this aldehyde decomposition, CH 4 and more CO were observed.…”

Study of the performance of Rh/La2O3–SiO2 and Rh/CeO2 catalysts for SR of ethanol in a conventional fixed-bed reactor and a membrane reactor

“…However, they require highly pure hydrogen as the cell electrodes are poisoned by even small amounts of CO [1]. Different approaches have been widely used to accomplish such a goal, involving integrated reaction units for CO clean-up such as: water-gas shift; CO selective oxidation; methanation [2]. Hydrogen-selective and -permeable Pd membranes are a promising technology for the production of H 2 with high purity.…”
