The study of the partial dehydrogenation (PDh) of Jet A-1 fuel on Pt-Sn/gamma-Al2O3 based catalysts to produce H2 to feed an on-board (aircraft) proton exchange membrane fuel cell is presented.

Abstract
The study of the partial dehydrogenation (PDh) of Jet A-1 fuel on Pt-Sn/gamma-Al2O3 based catalysts to produce H2 to feed an on-board (aircraft) proton exchange membrane fuel cell is presented. Exstensive physico-chemical characterisation of 5 wt% Pt and 1 wt% Sn pelleted materials has been performed, evidencing a higher concnetration of Pt on the outer part of the pellet, whereas Sn has been detected only on the external part. The investigated materials are active as catalysts for the PDh of normal and desulfurised Jet A-1 kerosene fuel. The presence of sulfur compounds and coke deposition strongly affects the H2 productivity which decreases rapidly with time-on-stream. The presence of a Na cation addition contributes to give the highest and most suitable H2 production. The condensed outlet liquid stream retains the fuel properties in the range of Jet A-1 kerosene fuel.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
