Resumo: The dry reforming reaction of methane comes as a promising process of syngas and hydrogen. Nickel catalysts on Al2O3 and SiO2 were synthesized by sol-gel method, with metalic load of 8% weight. The catalysts were characterized by temperature programmed reduction (TPR), termogravimetry analysis (TGA) and specific surface area measurements (BET). The dry reforming reaction was performed in a micro reactor packed with 500 mg of catalyst, previously activated in atmosphere of hydrogen. The dry reforming tests were done at 800oC and atmospheric pressure by a period of 12 hours, with a molar ratio in the feeding of [CO2:CH4] = 6. The products of the reaction were analyzed by gas chromatograph. The Ni-SiO2 catalysts showed better performance

Neste sentido, foram preparados catalisadores de níquel-sílica e níquel-alumina pelo método sol-gel, com carga metálica nominal de 8% em massa. Os catalisadores foram caracterizados por redução à temperatura programada, análise termogravimétrica e determinação da área superficial específica. A reação de reforma do metano com CO2 foi realizada em um micro-reator contendo 500 mg de catalisador, previamente ativado em uma mistura redutora contendo hidrogênio. Os ensaios de reforma a seco do metano foram realizados a 800C, na pressão atmosférica, por um período de 12 horas, com uma razão molar de alimentação de [CO2:CH4] = 6. Os produtos da reação foram analisados por cromatografia gasosa. Dentre os catalisadores avaliados, nas condições de reação estudadas, o catalisador de níquel suportado em sílica foi o que apresentou o melhor desempenhoUniversidade Estadual De Maringá2008-03-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/149210.4025/actascitechnol.v27i1.1492Acta Scientiarum.
