CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe partial dehydrogenation of hydrocarbon blends may be a suitable way to produce H2 on-board of automotives or airplanes to feed fuel cells and produce electric power, avoiding storage problems. In this work very interesting data have been collected using Jet A-1 surrogate and Pt-Sn/gamma-Al2O3 catalysts, operating at 450°C and feeding the vaporised hydrocarbon blend without any carrier gas. The use of Pt-Sn catalyst with 1:1 (w/w) ratio leads to the best compromise between activity and stability with time-on-stream, due to the formation of Pt-rich alloys. Neverthless, all studied catalysts exhibited limited thio-tolerance. In optimized reaction conditions, H2 productivity of 3000 NL/kg cat/h, sufficient to produce 3 kW of electric power, considering purification steps and a fuel efficiency of 50%, was obtained.

| Abstract: | The partial dehydrogenation of hydrocarbon blends may be a suitable way to produce H2 on-board of automotives or airplanes to feed fuel cells and produce electric power, avoiding storage problems. In this work very interesting data have been collected using Jet A-1 surrogate and Pt-Sn/gamma-Al2O3 catalysts, operating at 450°C and feeding the vaporised hydrocarbon blend without any carrier gas. The use of Pt-Sn catalyst with 1:1 (w/w) ratio leads to the best compromise between activity and stability with time-on-stream, due to the formation of Pt-rich alloys. Neverthless, all studied catalysts exhibited limited thio-tolerance. In optimized reaction conditions, H2 productivity of 3000 NL/kg cat/h, sufficient to produce 3 kW of electric power, considering purification steps and a fuel efficiency of 50%, was obtained. | |
