Resumo: Methodologies of ZSM-5 zeolite synthesis proposed in the literature were evaluated. Characterization of the synthesized samples was done by atomic absorption, infrared spectroscopy, X-ray diffraction and surface area analysis. Several parameters, such as source and order of addition of reagents, nature of template, molar ratios in the reaction medium, seeding, time and temperature of crystallization, were analyzed. The use of ethanol instead of nitrogenated templates, combined with the use of a seed proportion well above that recommended in the literature led to a methodology of ZSM-5 synthesis that was found to be productive and with good reproducibility. The characterization of the obtained samples confirmed the production of ZSM-5 zeolite with a good crystallinity. The synthesized zeolites have been used successfully as crystallization seeds in new syntheses.

A caracterização das amostras sintetizadas foi feita por absorção atômica, espectroscopia no infra-vermelho, difração de raios X e análise de área superficial. Diversos parâmetros foram envolvidos, como fonte e ordem de adição dos reagentes, tipo de direcionador de estrutura, razões molares no meio reacional, utilização de sementes, tempo e temperatura de cristalização. A utilização de etanol em substituição aos direcionadores nitrogenados, aliada ao emprego de sementes em proporção bem superior ao indicado na literatura, levou a uma metodologia de síntese de ZSM-5 que se mostrou produtiva e com boa reprodutibilidade. As caracterizações das amostras obtidas confirmaram a obtenção da zeólita ZSM-5, com boa cristalinidade. As zeólitas sintetizadas puderam ser utilizadas com sucesso como sementes de cristalização em novas sínteses.Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/300710.4025/actascitechnol.v22i0.3007Acta Scientiarum.
