The effect of Ti and Al incorporation to FSM-16 framework as the support of Ni catalysts on their catalytic performance in the reaction of dry reforming of methane (DRM) was investigated. A series of Ni/M-FSM-16 (M = Al, Ti) with M/Si molar ratio = 100, 50, 20 were synthesized via double-solvent impregnation of Nickel. Fresh catalysts were characterized using N2adsorption/desorption, XRD, FTIR, FE-SEM, H2-TPR analyses. The prepared catalyst went through DRM reaction at 750, 800, and 850 °C. The spent catalysts of best catalytic performance, i.e. Ni/Al50-FSM-16 and Ni/Ti100-FSM-16, were analyzed by FT-IR and O2-TPO to characterized carbonaceous deposits. Based on TPR results, the promotion of DRM performances was related to the strength of Ni interaction with supports to which Ti or Al was incorporated. Conversion of CH4 and CO2, and H2/CO ratio of the products via Ni/Al50-FSM-16 catalyst were promoted by 95%, 83%, 25% with respect to Ni/FSM-16 at 850 °C, respectively.
