Resumo: | From the economic point of view it is important to process high charges of solid in enzimatic hydrolysis of the lignocellulosic residues for the production of 2G ethanol, but batch operation with high initial charges of substrate can cause inefficient mixture, damaging the reactional process. An attractive alternative is operating the reactors in fed batch. The aim of this work was to determine, applying the theory of optimal control, the optimal feeding profile of substrate in bench reactor. For this, it was tested two kinetic of Michaelis-Menten: pseudo-homogeneous Michaelis-Menten kinetic and Michaelis Menten kinetic with inhibition by the product, in the last kinetic was obtained the best fit to experimental data. The developed algorithm was run in Matlab® software and the simulation results were experimentally validated. Enzymatic hydrolysis assays were performed with hydrothermally pre-treated sugar cane straw followed by the alkaline delignification. It was obtained good fiting of the simulation data with respect to the experimental data, with values of glucose final concentration close to 164.647 g/L (triplicate average) and in simulation the concentration was 174.93 g/L. Proving that the sugar cane straw, besides being a good feedstock cheap and abundant, it has a great energetic potential. Furthermore, the optimal control strategy was very efficient in optimization of the proposed problem. |

Uma alternativa atraente é operar os reatores em batelada alimentada. O objetivo deste trabalho foi determinar, aplicando a teoria do controle ótimo, o perfil ótimo de alimentação de substrato em reator de bancada. Para isso, foram testadas duas cinéticas de Michaelis-Menten, a cinética de Michaelis Menten psêudo-homôgenea e a cinética de Michaelis Menten com inibição competitiva pelo produto, onde nesta última cinética foi obtido o melhor ajuste aos dados obtidos experimentalmente. O algoritmo desenvolvido foi executado no software Matlab® e os resultados das simulações foram experimentalmente validados. Os ensaios de hidrólise enzimática foram realizados com palha de cana-de-açúcar pré- tratada hidrotérmicamente, seguido pela deslignificação alcalina com NaOH. Foram obtidos bons ajustes dosdados simulados com respeito aos dados experimentais, com valores de concentração final de glicose de 164,647 g / L (média da triplicata) e na simulação a concentração foi 174,93 g / L. Provando que a palha de cana-de-açúcar, além de ser uma matéria-prima barata e abundante, tem um grande potencial energético. Além disso, a estratégia de controle ótimo foi eficiente na otimização do problema proposto.Submitted by JÚLIO HEBER SILVA (julioheber@yahoo.com.br) on 2017-03-02T19:40:52Z No. of bitstreams: 2 Dissertação - Vitor Debiazzi Pereira Pinto - 2016.pdf: 2426609 bytes, checksum: f2521c3bf3a568b508c24d06c318197a (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-03-03T11:37:17Z (GMT) No. of bitstreams: 2 Dissertação - Vitor Debiazzi Pereira Pinto - 2016.pdf: 2426609 bytes, checksum: f2521c3bf3a568b508c24d06c318197a (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-03-03T11:37:17Z (GMT).
