Resumo: | Currently there is great concern about the consumption of fossil fuels, as well as a possible depletion of traditional sources of production of raw materials mainly hydrocarbon derivatives. Parallel challenges to the preservation of the environment bring to discussions agenda every question involving biofuels and their means of obtaining. That said this issue still has major concerns about the use of raw materials that require less energy expenditure and prevent competition for land for food production, which end up entering the agenda of externalities related with this issue. In the case of the production of ethanol from starch sources, traditional processes still have high costs associated with the production of enzymes used and the great energy demand for starch gelatinisation at high temperatures. An alternative to the granular starch hydrolysis process is the use of enzymes capable of processing these starches at low temperatures which makes it unnecessary to gelatinization and reduces energy expenditure, also called simultaneous saccharification and fermentation (SSF), resulting in considerable economic advantage. Brazil is a traditional agricultural producer, and the rice production is quite significant and is as a by-product of rice bran that has low commercial value, being used for oil extraction, as an ingredient in animal feed and as fertilizer organic therefore be in perfect conditions to be used as raw starchy material to obtain ethanol. This work aims to investigate the use of this raw material and set the parameters for increased production scale-up with the use of commercial enzymes. The initial data to establish the working parameters were taken from the literature establishing this initial data for testing. In view of the large number of variables used to Plackett-Burman methodology to verify the effects of the main variables and select the ones that have most effect on the model.Thus for the job 1 in the shake flasks were selected following parameters: concentration of bran inoculum percentage, corn percentage of water macerated, soybean concentration, enzyme percentage yeast addition time and percentage of cellulase. This initial planning, among the most significant variables and, consequently, were selected for the planning application Outlining Central Composite Rotational (CCRD), are rice bran concentration, the percentage of inoculum and the percentage of cellulase. To work 2 were investigated variables agitation and temperature in ethanol production in bioreactor 3 liters. For analysis of the experiment of reducing sugar was used DNS method (Miller, 1959), and analysis of the ethanol present in the sample specimens were removed and subjected to Alcolyzer. For the tests performed in the first work the greatest amount of ethanol was obtained at 12 assay which was reached 172.70 grams of ethanol per kilogram of rice bran with 84% efficiency in the experiment. For experiments performed in the second study, with 3 liter reactor the best result is shown in Test 1 reaching 182.52 grams of ethanol per kilogram of rice bran with 89% efficiency. Thus, it was demonstrated that there is considerable potential for the production of ethanol using this raw material. Taking into account that the availability of this raw material is estimated at 1 million tonnes per year, the IRGA, we would have a much ethanol around 35 to 50 million liters per year. |

Paralelamente a isso, os desafios com a preservação do meio ambiente trazem para as discussões questões que envolvem os biocombustíveis e seus meios de obtenção. Isso posto, essa questão ambiental ainda traz grandes preocupações referentes à utilização de matérias primas que exijam menos gastos energéticos, bem como evitar a disputa por terras destinadas à produção de alimentos, o que acaba entrando na pauta das externalidades envolvendo o tema. No caso da produção de etanol de fontes amiláceas, os processos tradicionais ainda apresentam elevados custos de produção associados às enzimas empregadas e à grande demanda energética para a gelatinização do amido com altas temperaturas. Uma alternativa ao processo de hidrólise do amido granular é a utilização de enzimas capazes de processar esses amidos a baixas temperaturas, o que torna desnecessária a gelatinização e reduz o gasto energético, também denominado sacarificação e fermentação simultânea (SSF), apresentando considerável vantagem econômica. O Brasil é um tradicional produtor agrícola, sendo que a produção de arroz é bem expressiva e tem como um dos subprodutos o farelo de arroz. Este subproduto possui baixa valor comercial e é utilizado para extração de óleo, além de funcionar como ingrediente de ração animal e como fertilizante orgânico, estando, portanto, em perfeitas condições para utilização como matéria-prima amilácea para obtenção de etanol. A partir disso, este trabalho visa investigar a utilização e a viabilidade técnica do farelo de arroz, com a utilização de enzimas comerciais. Os dados iniciais para estabelecer os parâmetros de trabalho foram retirados da literatura. Tendo em vista o grande número de variáveis, utilizou-se a metodologia Plackett-Burman, visando verificar os efeitos das principais variáveis e selecionar as que tiveram maior efeito sobre o modelo. Dessa forma para o trabalho 1 em frascos agitados foram selecionadas as seguintes variáveis: concentração de farelo, percentual de inoculo, percentual de água de milho macerada, concentração de farelo de soja, percentual de enzima, tempo de adição de levedura e percentual de celulase. Desse planejamento inicial, entre as variáveis mais significativas e que, consequentemente, foram selecionadas para a aplicação do planejamento Delineamento Composto Central Rotacional (DCCR), estão a concentração de farelo de arroz, o percentual de inoculo e o percentual de celulase. Para o trabalho 2 em biorreator de 3 litros, foram investigadas as variáveis agitação e temperatura na produção de etanol. Para análise do açúcar redutor dos experimento foi utilizado a metodologia de DNS (Miller, 1959), e para análise do etanol presente nos ensaios foram retirados amostras e submetidas ao Alcolyzer. Para os ensaios realizados no primeiro trabalho a maior quantidade de etanol foi de 172,70 gramas de etanol por quilograma de farelo de arroz, com eficiência de 84%. Para os experimentos realizados no segundo trabalho, com reator de 3 L o melhor resultado foi 182,52 gramas de etanol por quilograma de farelo de arroz com eficiência de 89 %.Dessa forma, foi demonstrado que existe um potencial considerável para produção de etanol utilizando esta matériaprima, tendo em vista que há a estimativa de 1 milhão de toneladas por ano, com a possibilidade de produção de 35 a 50 milhões de litros adicionais de etanol por ano.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaProdução de etanolFarelo de arrozHidrólise de amidoEthanol productionRice branStarch hydrolysisCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLAViabilidade técnica da produção de etanol a partir de farelo de arrozTechnical viability of ethanol production from rice braninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisMazutti, Marcio Antoniohttp://lattes.cnpq.br/3520282081196395Ferraz, Rafael Camargohttp://lattes.cnpq.br/9975610954564787Mayer, Flávio Diashttp://lattes.cnpq.br/4268416135140359Mallmann, Evandro Stoffelshttp://lattes.cnpq.br/3624152453898910Souza, Angélica Rossana Castro dehttp://lattes.cnpq.br/8602678448190256http://lattes.cnpq.br/3455281174299781Michel Junior, Raul José dos Santos5003000000084003003003003003003007d7d5001-84cd-4e08-9476-4ab9b3d8e954b3f85272-7ea0-47c5-bfe6-ad1a2ec53903095af8fc-4632-46fe-b665-8f517f1a58d9a2b31fb8-f91b-4155-af63-e4a849dd148b6c43c8b9-1067-45e5-b26a-685be4d5706376dea441-6b20-4d01-b067-b82f40c2a00dinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALMICHEL JUNIOR, RAUL JOSE DOS SANTOS.pdfapplication/pdf2046569http://repositorio.ufsm.br/bitstream/1/3643/1/MICHEL%20JUNIOR%2c%20RAUL%20JOSE%20DOS%20SANTOS.pdf0143eb6dbd13aeb5904847c2745d0d35MD51TEXTMICHEL JUNIOR, RAUL JOSE DOS SANTOS.pdf.txtMICHEL JUNIOR, RAUL JOSE DOS SANTOS.pdf.txtExtracted texttext/plain132815http://repositorio.ufsm.br/bitstream/1/3643/2/MICHEL%20JUNIOR%2c%20RAUL%20JOSE%20DOS%20SANTOS.pdf.txt48dc8339479b836a16977e07e2eda3aaMD52THUMBNAILMICHEL JUNIOR, RAUL JOSE DOS SANTOS.pdf.jpgMICHEL JUNIOR, RAUL JOSE DOS SANTOS.pdf.jpgIM Thumbnailimage/jpeg4163http://repositorio.ufsm.br/bitstream/1/3643/3/MICHEL%20JUNIOR%2c%20RAUL%20JOSE%20DOS%20SANTOS.pdf.jpg88f63b3fa655c994de090c4c93df4e7eMD531/36432022-03-30 08:20:31.812oai:repositorio.ufsm.br:1/3643Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-03-30T11:20:31Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
