Resumo: Este trabalho descreve um estudo sobre a síntese da perovsquita LaNiO3 via método do gel proteico, variando quantidade de colágeno e sobre a atividade catalítica de LaNiO3 e LaNiO3/Al2O3 na produção de gás de síntese (CO + H2). Os padrões de difração de raios X revelaram a formação da estrutura perovsquita em todas as amostras preparadas pelo método de síntese do gel protéico, variando a quantidade de colágeno e após calcinações a 700 ºC por 2 h. O catalisador LaNiO3/Al2O3 preparado pelo método de impregnação mostrou picos de difração nos difratogramas atribuídos a LaNiO3 e ao suporte (Al2O3). Este catalisador apresentou: área superficial específica de 46,1 m2 g-1, dois picos de redução no perfil de redução à temperatura programada (RTP) e 46% de conversão do metano (através da oxidação parcial do metano utilizando oxigênio) depois de 18 h de reação. _________________________________________________________________________________________ ABSTRACT: This work describes a study on the synthesis of LaNiO3 perovskites via the modified proteic gel method, varying collagen content and on the catalytic activity of LaNiO3 and LaNiO3/Al2O3 in the syngas (CO + H2) production. X-ray diffraction patterns revealed the formation of perovskite structure in all samples prepared by proteic gel synthesis method, varying collagen content and after calcinations at 700 ºC for 2 h. LaNiO3/Al2O3 catalyst prepared by the impregnation method showed diffraction peaks due to the perovskite structure and to the support (Al2O3). This catalyst presented: specific surface of 46.1 m2 g-1, two reduction peaks in the temperature programmed reduction (TPR) profile and 46% of methane conversion (by the partial oxidation of methane using oxygen) after 18 h of reaction.
