Abstract

n-Hexadecane hydroisomerization at 220 °C and 30 bar was used as a model reaction for comparing the catalytic performances of a Pt/HBEA sample whose zeolite crystals were germinated on an α alumina surface with those of 1Pt/HZM-22 catalyst well-known for its high isodewaxing selectivity. Similar values of selectivity to isomers were obtained with both catalysts even at high conversions. Moreover, despite its low zeolite content (13 wt%), the Pt/HBEA Al2O3 catalyst had the important advantage to be 4.6 times more active.
