| Abstract: Pt/SAPO-11 catalysts were prepared by impregnation using different polymer dispersants, and their structural and acidic properties were analyzed and characterized using techniques such as X-ray diffraction (XRD), transmission electron microscopy (TEM), N2 adsorption-desorption, and NH3 temperature-programmed desorption (TPD). The results showed that the dispersants did not destroy the structure of the catalysts, but instead increased their pore volumes, pore sizes, and specific surface areas, while also changing the acid strengths and acid amounts of the zeolites. Among the dispersants used in our work, polyvinyl pyrrolidone (PVP) treatment resulted in the optimal pore volume, pore size, and acid distribution for the Pt/SAPO-11 catalyst. Evaluation of the catalytic performance of the Pt/SAPO-11 catalysts treated with different dispersants in a fixed-bed reactor showed that the PVP-treated Pt/SAPO-11 catalyst also exhibited the best catalytic performance, with a hydrogenation deoxygenation rate of Jatropha oil up to 99.45%, and bio -aviation kerosene component yield and isoparaffins (C8-C16) selectivity reaching 44.67% and 56.37%, respectively. |
