Resumo: | This study proposes to verify the efficiency of the treatment of corn straw with different ILs when increasing the fermentable sugars content. Therefore, the alkaline pulping process of the straw was carried out, with lignin contents of 8.30% and 3.20% and holocellulose of 66.79% and 95.26% in raw and pulp straw, respectively, besides the synthesis and characterization of the sec-butylammonium acetate, sec-butylammonium lactate, n-butylammonium acetate and n-butylammonium lactate. Afterward, the treatment of the raw and pulped straw was carried out with the ILs and subsequent enzymatic hydrolysis. A glucose mass ratio of up to 17.57% was verified in the pulp straw and treated with n-butylammonium acetate, against, 3.98% in the only pulped straw and an increase of up to 90.7% in the mass ratio of fermentable sugars in the treated straw compared to the untreated straw. This efficiency is greater when using ionic liquids with the n-butylammonium cation. |

Assim, inicialmente, foi realizado o processo de polpação alcalina da palha, sendo verificados teores de lignina de 8,30 % e 3,20 % e de holocelulose de 66,79 % e 95,26 % nas palhas bruta e polpada, respectivamente, além da síntese e caracterização dos LIs acetato de sec-butilamônio, lactato de sec-butilamônio, acetato de n-butilamônio e lactato de n-butilamônio. Posteriormente, foi realizado o tratamento das palhas bruta e polpada com os LIs e hidrólise enzimática, sendo verificada uma razão mássica de glicose de até 17,57% na palha polpada e tratada com o acetato de n-butilamônio, contra 3,98% na palha somente polpada e, um aumento de até 90,7% na razão mássica de açúcares fermentescíveis na palha tratada, em relação, a palha sem tratamento, sendo esta eficiência, maior, ao utilizar-se líquidos iônicos com o cátion n-butilamônio.Universidade Federal de Viçosa - UFV2017-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/244694160302201713010.18540/jcecvl3iss2pp130-143The Journal of Engineering and Exact Sciences; Vol. 3 No. 2 (2017); 130-143The Journal of Engineering and Exact Sciences; Vol. 3 Núm. 2 (2017); 130-143The Journal of Engineering and Exact Sciences; v. 3 n. 2 (2017); 130-1432527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2446941603022017130/pdfMorandim-Gianetti, Andreia de AraújoCampos, Patrícia dos ReisViana, AndréMartinez, Rafaela Paz TrujilloDominato, MárcioSilva, Rosianne CristinaSantoro, Murilo Albuixechinfo:eu-repo/semantics/openAccess2020-07-14T22:33:05Zoai:ojs.periodicos.ufv.br:article/2309Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2020-07-14T22:33:05Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false |
