Conversão catalítica do etanol sobre catalisadores suportados em ZSM-5

Abstract: ResumoO petróleo, fonte de energia não renovável, é a principal matéria-prima usada na produção de derivados como combustíveis, lubrificantes e petroquímicos básicos. Neste contexto o etanol, uma matéria-prima renovável, torna-se fonte para a obtenção de hidrocarbonetos de maior valor agregado, tais como, benzeno, tolueno, etc. Este trabalho teve como objetivo avaliar o efeito de diferentes metais suportados em zeólita HZSM-5 para a conversão do etanol em produtos com maior valor agregado. Duas séries de catal… Show more

“…It is possible to see two NH 3 desorption peaks in the TPD-NH 3 analysis, where the first peak (~218 • C, corresponding to weak and moderate acidic sites) and the second peak (~525 • C) are attributed to acidic sites of a strong nature. These results are in agreement with the literature [56,57]. The acidity of the ZnO-Ni0.5Zn0.5Fe2O4 catalyst, heat-treated at 800 °C, was calculated by integrating the deconvolution area from the TPD-NH3 curve.…”
