Pt supported on amorphous silico alumina (Pt/ASA) was studied as a catalyst for glycerol hydrogenolysis (dehydration + hydrogenation) to 1,2-propanediol under mild operation conditions (493 K and 45 bar H-2 pressure) Glycerol hydrogenolysis also took place in experiments performed under N-2 pressure clue to hydrogen available from glycerol aqueous phase reforming As both acid and metallic sites are involved in this process a study including activity tests and different characterization techniques (TPR and FTIR of adsorbed pyridine, NH3-TPD, XPS and TGA) were applied to this catalytic system (ASA support and Pt/ASA catalyst) in order to get a deeper understanding about their interactions (C) 2010 Elsevier B V All rights reserved
