【 摘 要 】

The importance of biogas was evidenced by the dry reforming reaction using a nickel catalyst supported: Al₂O₃, SiO₂, MCM 41 and La₂O₃. The catalysts were characterized using electron scanning microscopy, Chemisorption, BET, X- Ray analysis.  The reaction was conducted in a quartz reactor, atmospheric pressure and at temperatures of 500, 600 and 700 ^oC. The catalysts showed different conversions in syngas with the change of temperature, and H₂/CO ratio variable. The nickel catalyst supported on alumina showed the most activity in the three reaction temperatures. The conversion of supported nickel catalysts, in the examined temperatures, decreased in the following order: Ni/Al₂O₃ ˃ Ni/La₂O₃ ˃ NiSi/O₂ ˃ Ni/MCM41. The Ni/Al₂O₃ and Ni/MCM-41 catalysts showed H₂/CO greater than one at all temperatures.
