X-ray diffraction (XRD), nitrogen adsorption-desorption, ammonia-temperature programmed desorption (NH₃-TPD), and pyridine-Fourier transform infrared (pyridine-FT-IR) spectroscopy analyses were performed to characterize V₂O₅/Al₂O_x with different V₂O₅ loadings. We conclude that a 20%-25% (w) V₂O₅ loading corresponds to the monolayer coverage of VO_x units over the surface of V₂O₅/Al₂O₃ according to the VO_x unit surface density values. The impregnation of V₂O₅ led to a decrease in the Lewis acidity of the alumina and the formation of Brønsted acid sites, which resulted from the V―OH groups of the oxidized VO_x units. With an increase in V₂O₅ loading the amount of Brønsted acid sites increased and reached a maximum at a V₂O₅ loading of about 20%. The influence of V₂O₅ loading in V₂O₅/Al₂O₃ on the oxidative activation performance during n-heptane catalytic cracking was studied. The results show that the highest promotion was obtained upon introducing V₂O₅/Al₂O₃ with a 20%-25% V₂O₅ loading into the HZSM-5 equilibrium catalyst. V₂O₅/Al₂O₃ (20%-25% V₂O₅) had a monolayer coverage of VO_x units over its surface and it provided the largest amount of surface lattice oxygen and thus the strongest oxidative activation toward n-heptane was achieved. The performance decreased when the V₂O₅ loading increased further because of the inhibited participation of surface lattice oxygen in the reaction, which was caused by the formation of bulk V₂O₅ and AlVO₄.
