Low temperature steam reforming of ethanol over supported noble metal catalystsLow temperature steam reforming of ethanol over supported noble metal catalysts Σύντομη Δημοσίευση σε Συνέδριο Conference Short Paper 2015-11-142011enThe catalytic activity of M/Al2O3 catalysts for the reaction of steam reforming of ethanol has been investigated in the temperature range of 300–450 °C. It has been found that the catalytic performance varies in the order of Pt > Pd > Rh > Ru, with Pt exhibiting high activity and selectivity toward hydrogen production, as well as long term stability at low temperatures. It is shown that the reaction occurs in a bifunctional manner, with the participation of both the dispersed metallic phase and the support. Ethanol interacts strongly with the Al2O3 carrier, promoting mainly ethanol dehydration, while in the presence of Pt, catalytic activity is shifted toward lower temperatures. Ethanol decomposition and dehydrogenation reactions dominate at low temperatures, while reforming, water-gas shift and methanation contribute significantly to product distribution.http://creativecommons.org/licenses/by/4.0/2-12International Conference on Hydrogen Production Panagiotopoulou Paraskevi Παναγιωτοπουλου Παρασκευη Verykios E.
