Resumo: Among the microporous materials used in heterogeneous catalysis, zeolites have become promising due to the relevant physicochemical and catalytic properties. Noteworthy is the zeolite ZSM-5 used as a catalyst in reactions in the areas of petrochemical and fine chemistry, such as cracking, isomerization, alkylation and aromatization reactions of olefins.  In view of this, the objective of this work was to synthesize the ZSM-5 zeolite, through binary mixtures of tetraethylammonium hydroxide (TEAOH) and different amines (n-butylamine, isobutylamine and diisobutylamine) acting as organic structure directing agents (SDA's). X-ray diffractometry indicated that only the reaction system containing TEAOH and n-butylamine provided the achievement of highly crystalline ZSM-5 and without competing phases. The nitrogen adsorption-desorption isotherms indicated that a material with a high surface area (329 m2·g-1) and pore volume (0.26 cm3·g-1) was obtained. Thus, it was possible to identify a new synthesis route in obtaining the ZSM-5 zeolite.

Destacando-se a zeólita ZSM-5utilizada como catalisador em reações nas áreas de petroquímica e química fina, como as reações de craqueamento, isomerização, alquilação e aromatização de olefinas. Diante disto, o objetivo deste trabalho foi sintetizar a zeólita ZSM-5, através de misturas binárias de hidróxido de tetraetilamônio (TEAOH) e diferentes aminas (n-butilamina, isobutilamina e diisobutilamina) atuando como agentes orgânicos direcionadores de estrutura (OSDA's). A difratometria de raios X indicou que apenas o sistema reacional contendo TEAOH e n-butilamina proporcionou à obtenção da ZSM-5 altamente cristalina e isenta de fases concorrentes. As isotermas de adsorção-dessorção de nitrogênio indicaram a obtenção de um material com elevada área superficial (329 m2·g-1) e volume de poros (0,26 cm3·g-1). Dessa forma, foi possível identificar uma nova rota de síntese na obtenção da zeólita ZSM-5.Universidade Federal de Viçosa - UFV2020-09-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1069510.18540/jcecvl6iss3pp0200-0206The Journal of Engineering and Exact Sciences; Vol. 6 No. 3 (2020); 0200-0206The Journal of Engineering and Exact Sciences; Vol. 6 Núm. 3 (2020); 0200-0206The Journal of Engineering and Exact Sciences; v. 6 n. 3 (2020); 0200-02062527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/10695/5907Copyright (c) 2020 The Journal of Engineering and Exact Sciencesinfo:eu-repo/semantics/openAccessPimentel de Sá da Silva, DiogoJosé Barros da Silva, BrunoOsimar Sousa da Silva, Antonio2021-02-23T20:12:27Zoai:ojs.periodicos.ufv.br:article/10695Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2021-02-23T20:12:27Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
