Effect of sulfosalicylic acid treatment on the properties of Beta zeolite (BEA and BEA-SA) and performance of NiW/Beta-Al2O3 catalysts in hexadecane hydrocracking have been studied. The acid treatment had almost no effect on porous structure of Beta zeolite while it resulted in significant changes in acidity. The decrease in concentration of Brønsted (35 to 25 μmol/g) and Lewis acid sites (119 to 54 μmol/g) was observed that could be related to the removal of extra framework aluminum. NiW/BEA-Al2O3 catalyst having zeolite with higher acidity demonstrated higher activity in hexadecane hydrocracking. The hexadecane conversion was 54.5–95.6% and 32.4–93.9% for NiW/BEA-Al2O3 and NiW/BEA-SA-Al2O3, respectively. However, NiW/BEA-SA-Al2O3 demonstrated higher selectivity to target products (C5-C15 hydrocarbons and iso-C16) than NiW/BEA-Al2O3 (63.8 and 14.4 % vs. 62.4 and 4.5 %, respectively) at similar hexadecane conversion of ∼95 %. This can be attributed mainly to the effect of sulfosalicylic acid treatment on Beta zeolite acidity.
