[Display omitted] ► We synthesized Pt-Sn/Al2O3 catalysts with addition of different dopants. ► Catalysts are for production of hydrogen by partial dehydrogenation of kerosene. ► BaO dopant modifies support acidity, prevents coke deposition, slows down deactivation. ► We obtained a productivity of 2000NLH2kgcat−1h−1 with H2 purity of 97vol.%. Production of hydrogen on-board an airplane, to feed a fuel cell secondary power generation unit, is realisable by catalytic partial dehydrogenation of kerosene. The influence of the nature support on the partial dehydrogenation of Ultra Low Sulfur Kerosene Jet A-1 using Pt-Sn based catalysts is investigated in this work. The doping of an alumina support with barium oxide leads to a catalyst providing a productivity of 2000NLH2kgcat−1h−1 with H2 purity of 97vol.%.
