Resumo: This study aimed to synthetize the LTA zeolite using Pinheiro clay state of Sergipe (LTA-PIN), currently limited clay for the production of ceramic artifacts, for CO2 adsorption in static system. The Pinheiro clay was treated with HCl for the removal of organic matter and metals. The LTAPIN zeolite was synthesized by two-step route using calcination followed by hydrothermal treatment. The characterization was performed using the techniques of XRD, XRF, SEM, TG/DTA and FT-IR. The main crystalline phases identified in Pinheiro clay were muscovite, ilite, calcite, montmorillonite and quartz. The crystalline restructuring of the clay was evidenced by XRD and the synthesis of LTA zeolite was verified by comparison with the crystallographic cards being obtained with 95.70% of purity. The CO2 adsorption experiments on LTA zeolite were performed using the static volumetric method performed at 25°C, for 1 h, by varying the initial CO2 pressure between 0.05-0.36 MPa using 2 g of adsorbent. The kinetic study showed that the adsorption of CO2 in the pores of the LTA-PIN zeolite occurs in the first 30 min and is best represented by the pseudo second order kinetic model with Qe of 101.26 mg g-1 and k2 of 0.0014 g mg-1 min-1 . The LTA-PIN zeolite presented adsorption capacity of 131.44 mg g-1 with chemical equilibrium described by the Langmuir isotherm indicating chemical adsorption and presenting high regenerative capacity.

A argila Pinheiro foi tratada com HCl para a remoção de matéria orgânica e de metais. A zeólita LTA foi sintetizada por rota com duas etapas, utilizando calcinação seguida de tratamento hidrotérmico. A caracterização foi feita mediante as técnicas de DRX, FRX, MEV, TG/DTA e FTIR. As principais fases cristalinas identificadas na argila Pinheiro foram muscovita, ilita, calcita, montmorilonita e quartzo. A reestruturação cristalina da argila foi evidenciada por DRX sendo comprovada a síntese de zeólita LTA por comparação com as fichas cristalográficas sendo obtida com 95,79% de pureza. Os ensaios de adsorção de CO2 em zeólita LTA foram realizados utilizando o método volumétrico estático realizados à temperatura de 25˚C, tempo de 1 hora, variando a pressão inicial de CO2 entre a faixa de 0,05-0,36 MPa utilizando 2 g de adsorvente. O estudo cinético mostrou que a adsorção de CO2 nos poros da zeólita LTA-PIN ocorre nos primeiros 30 minutos sendo melhor representada pelo modelo cinético de pseudosegunda ordem apresentando Qe de 101,26 mg g-1 e k2 de 0,0014 g mg-1 min-1 . A zeólita LTA-PIN apresentou capacidade adsortiva de 131,44 mg g-1 com equilibrio químico descrito pela isoterma de Langmuir indicando adsorção química e apresentando alta capacidade regenerativa.Fundação de Apoio a Pesquisa e à Inovação Tecnológica do Estado de Sergipe - FAPITEC/SESão CristóvãoporEngenharia químicaZeolitosArgilaDióxido de carbonoSergipe (SE)Zeólita LTAArgila PinheiroCO2LTA zeolitePinheiro clayENGENHARIAS::ENGENHARIA QUIMICACO2 em zeólita LTA obtida de argila pinheiro do Estado de Sergipeinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPós-Graduação em Engenharia QuímicaUniversidade Federal de Sergipe (UFS)reponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessLICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/17806/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALVICTOR_HUGO_SANTOS_RAMOS.pdfVICTOR_HUGO_SANTOS_RAMOS.pdfapplication/pdf2474637https://ri.ufs.br/jspui/bitstream/riufs/17806/2/VICTOR_HUGO_SANTOS_RAMOS.pdf8d7ca775cef1b84b5354ff35ae010724MD52TEXTVICTOR_HUGO_SANTOS_RAMOS.pdf.txtVICTOR_HUGO_SANTOS_RAMOS.pdf.txtExtracted texttext/plain98773https://ri.ufs.br/jspui/bitstream/riufs/17806/3/VICTOR_HUGO_SANTOS_RAMOS.pdf.txt397365410805a58114bdecd795a63f31MD53THUMBNAILVICTOR_HUGO_SANTOS_RAMOS.pdf.jpgVICTOR_HUGO_SANTOS_RAMOS.pdf.jpgGenerated Thumbnailimage/jpeg1259https://ri.ufs.br/jspui/bitstream/riufs/17806/4/VICTOR_HUGO_SANTOS_RAMOS.pdf.jpg2664af8e88dc5b210ad2e8ef1e82ebe9MD54riufs/178062023-07-06 18:51:20.768oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2023-07-06T21:51:20Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false
