Influence of Nature Support on Methane and CO(2) Conversion in a Dry Reforming Reaction over Nickel-Supported Catalysts
A promising method to reduce global warming has been methane reforming with CO(2), as it combines two greenhouse gases to obtain useful products. In this study, Ni-supported catalysts were synthesized using the wet impregnation method to obtain 5%Ni/Al(2)O(3)(SA-5239), 5%Ni/Al(2)O(3)(SA-6175), 5%Ni/...

description | A promising method to reduce global warming has been methane reforming with CO(2), as it combines two greenhouse gases to obtain useful products. In this study, Ni-supported catalysts were synthesized using the wet impregnation method to obtain 5%Ni/Al(2)O(3)(SA-5239), 5%Ni/Al(2)O(3)(SA-6175), 5%Ni/SiO(2), 5%Ni/MCM41, and 5%Ni/SBA15. The catalysts were tested in dry reforming of methane at 700 °C, 1 atm, and a space velocity of 39,000 mL/gcat h, to study the interaction of Ni with the supports, and evaluation was based on CH(4) and CO(2) conversions. 5%Ni/Al(2)O(3)(SA-6175) and 5%Ni/SiO(2) gave the highest conversion of CH(4) (78 and 75%, respectively) and CO(2) (84 and 82%, respectively). The catalysts were characterized by some techniques. Ni phases were identified by X-ray diffraction patterns. Brunauer–Emmett–Teller analysis showed different surface areas of the catalysts with the least being 4 m(2)/g and the highest 668 m(2)/g belonging to 5%Ni/Al(2)O(3)(SA-5239) and 5%Ni/SBA15, respectively. The reduction profiles revealed weak NiO-supports interaction for 5%Ni/Al(2)O(3)(SA-5239), 5%Ni/MCM41, and 5%Ni/SBA15; while strong interaction was observed in 5%Ni/Al(2)O(3)(SA-6175) and 5%Ni/SiO(2). The 5%Ni/Al(2)O(3)(SA-6175) and 5%Ni/SiO(2) were close with respect to performance; however, the former had a higher amount of carbon deposit, which is mostly graphitic, according to the conducted thermal analysis. Carbon deposits on 5%Ni/SiO(2) were mainly atomic in nature. |
