Ni/ZSM-5 modified Nano catalyst containing 3, 5 and 7wt. % Ni were prepared byimpregnation method for DRM. Dealumination of ZSM-5 carried out by HNO3 solution as adealumination agent. This process led to increase Si/Al ratio for ZSM-5. For approaching to the higherconversion and H2/CO ratio, higher concentration of acid and lower temperature for treatment ofZSM-5 must be used. The sample that was prepared by higher concentration of acid and lowertemperature in dealumination process, with 5%wt Ni showed a better activity and stability thanunmodified sample during DRM at 700°C for 30h time on stream.
