Resumo: It was studied the removal of toxic inhibitors produced during dilute-acid pretreatment of lignocellulosic biomass. Different sulfuric acid concentrations (1%, 2.5% and 5%) and reaction times (15, 30 and 60 minutes) were analyzed for the pretreatment process, and, 1% w/w H2SO4 and 15-minute reaction time have proven to be the most proper condition. With the experimental data, purification and concentration operations were simulated. For C5 stream (xylose, furfural and water) three different unit operations have been explored: a flash drum, a distillation column and a distillation column followed by multiple-effect evaporators. The distillation column with five multiple-effect evaporator system achieved the best energy efficiency (0,85 kW/kg xylose) and removal of furfural. For C6 stream (glucose and water), a four multiple-effect evaporator system simulated showed that the energy requirements not change significantly within the range of sugar concentration used (14% to 20%).

Experimentalmente estudaram-se no pré-tratamento diferentes concentrações de H2SO4 (1%, 2,5% e 5%) e tempos de reação (15, 30 e 60 minutos). Definiu-se como condição mais adequada 1 % m/m de ácido sulfúrico e 15 minutos como tempo de reação. Com os dados experimentais realizou-se a simulação da remoção do furfural e da concentração dos açúcares. As correntes contendo açúcares foram denominadas de C5 (hidrolisado ácido – xilose e furfural) e C6 (hidrolisado enzimático - glicose). A corrente C5 foi purificada e concentrada através de uma coluna de enchimento integrada a evaporadores múltiplos com cinco efeitos, com gasto energético de 0,85 kW/kg de xilose. Para concentrar a corrente C6 de 14 a 20% de açúcares utilizaram-se evaporadores múltiplos com quatro efeitos com gasto energético requerido de 0,34 kW/ kg de glicose.Universidade Federal de Viçosa - UFV2017-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/244694160302201709510.18540/jcecvl3iss2pp095-111The Journal of Engineering and Exact Sciences; Vol. 3 No. 2 (2017); 095-111The Journal of Engineering and Exact Sciences; Vol. 3 Núm. 2 (2017); 095-111The Journal of Engineering and Exact Sciences; v. 3 n. 2 (2017); 095-1112527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2446941603022017095/pdfLucarini, Adriana CéliaFerreira, Newton Libâniode Souza, Charles DouglasFrancisco, Felippe Pinheiro LimaFonseca, Isabela ReinaudRossi, Larissa GuedesFerreira, Vanuza Magalhãesinfo:eu-repo/semantics/openAccess2020-07-14T22:30:57Zoai:ojs.periodicos.ufv.br:article/2306Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2020-07-14T22:30:57The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
