Abstract Bi-metallic (Pt–Sn and Sn–Ni) and tri-metallic (Pt–Sn–Ni) catalysts, supported on Al-containing hexagonal mesoporous silica (Al-HMS) (Si/Al = 20) materials, were synthesized. N 2 adsorption–desorption, X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) test, and temperature programed desorption (NH 3 -TPD) were used to characterize physicochemical characteristics and textural properties of the Al-HMS catalysts. Catalytic performances on hydro-cracking of n -decane at different reaction conditions were studied in a micro-reactor. Comparison between Pt–Sn, Sn–Ni and Pt–Sn–Ni catalyst under different hydro-cracking conditions was made. The experimental results indicate that the proper balance between the acid and metal functions is the key in synthesizing a catalyst with a better performance in hydro-cracking. Tri-metallic catalyst exhibits the best catalytic performance in n -decane hydro-cracking than two bi-metallic catalysts.
