Resumo: MCM-36 zeolite was prepared with initial Si/Al molar ratio of 50. The MCM-22 zeolite with Si/Al ratio of 50 was prepared for comparison. Both zeolites were characterized by several techniques: Chemical Analysis by Atomic Absorption Spectroscopy (AAS), X-Ray Diffraction (XRD), Textural Analysis by N2 and Ar Adsorption, Scanning Electronic Microscopy (SEM) and Infrared Spectrometry (IR). The MCM-36 material is obtained from pillarization of the MCM-22 zeolite precursor material with Si. It was observed that pillarization process provided an increase of basal spacing from 27,5 to > 45 Å and of specific superficial area from 430 to 810m2/g. The MCM-36 material is formed by layers, with a porous system formed by sinusoidal channels of 10MR, separated by pillars that provide a formation of additional mesoporous in a range of 25 Å.

A zeólita MCM-36 foi preparada com relação molar inicial de Si/Al de 50, e zeólita MCM-22 com relação molar Si/Al de 50 foi preparada para critérios de comparação. Ambas as zeólitas foram caracterizadas por diversas técnicas: Análises Químicas por Espectroscopia de Absorção Atômica (EAA); Difração de Raios X (DRX); Análises Texturais por Adsorção de N2 e Ar; Microscopia Eletrônica de Varredura (MEV) e Espectrometria no Infravermelho (IV). O material MCM-36 é obtido pela pilarização do precursor da zeólita MCM-22 com silício. Foi observado que o processo de pilarização proporcionou um aumento do espaçamento basal de 27,5 para >45Å e da superfície específica de 430 para 810m2/g. O material MCM-36 é constituído por lâminas, com um sistema de poros de canais sinusoidais de 10MR, separadas por pilares que dão lugar à formação de mesoporos adicionais em uma ampla faixa com cerca de 25Å.Universidade Estadual De Maringá2008-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/225210.4025/actascitechnol.v25i1.2252Acta Scientiarum.
