Resumo: | The oil shale ash, by-product of the Petrosix process, was used as raw material to synthesize zeolite-type materials. The synthesis procedure was the alkaline fusion followed by refluxing, with three different starting material compositions. Two products were selected and chemically, structurally and morphologically analyzed. The compound (1) was obtained from the composition 3SiO2.Al2O3.5,7Na2O.228H2O after 2h30min of refluxing, presented the largest Na-X zeolite crystallinity, while the compound (2), produced with the composition 3SiO2.Al2O3.10,5Na2O.325H2O after 30min of refluxing, obtained the largest Na-A zeolite content. The products were characterized by X-ray diffraction, physical adsorption of nitrogen, X-ray fluorescence, 29Si nuclear magnetic resonance and scanning electron microscopy. The results showed that all Si and Al present in the zeolite-type compounds were in the crystalline form, and the SEM micrographies indicated the presence of cubic crystals of Na-A and -X zeolites structures. |

O procedimento de síntese adotado foi a fusão alcalina seguida de refluxo, utilizando-se três composições de mistura reagente. Dois produtos foram selecionados e analisados química, estrutural e morfologicamente. O composto (1) foi obtido a partir da composição 3SiO2.Al2O3.5,7Na2O.228H2O após 2h30min de refluxo, apresentando a maior cristalinidade quanto à zeólita X, enquanto o composto (2), produzido com a composição 3SiO2.Al2O3.10,5Na2O.325H2O após 30min de refluxo, obteve o maior teor de zeólita A. Os produtos foram caracterizados por difração de raios X, fisissorção de nitrogênio, fluorescência de raios X, ressonância magnética nuclear de 29Si e microscopia eletrônica de varredura. Os resultados mostraram que todo Si e Al presentes nos materiais zeolíticos estão sob a forma cristalina, e as micrografias indicaram a presença dos cristais cúbicos das estruturas das zeólitas A e X.Universidade Estadual De Maringá2008-03-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/128310.4025/actascitechnol.v28i1.1283Acta Scientiarum.
