Reforma a vapor do etanol sobre catalisadores de Co - Ni/MgAl2O4: propriedades estruturais e catalíticas em função da temperatura de reação
(Universidade Federal de São Carlos, 2016-08-05)
This thesis studied the effect of Co addition to Ni-based catalysts, focused on electronic and structural modification, as well as how these changes interfere on the catalytic properties, like reaction pathway and carbon ...
Assesment of alternative routes for sugarcane-based ethanol recovery: exergy and economic analysis
(Universidade Federal de São Carlos, 2018-02-28)
The aim of this thesis was to develop a methodological approach that can systematically guide process simulation for better understanding of bioethanol production process. In the present work, the ethanol production process ...
Estudo da produção de etanol a partir de xilose e xilooligômeros usando xilanases, xilose isomerase e levedura co-imobilizadas
(Universidade Federal de São Carlos, 2019-04-24)
The production of ethanol from xylose with the yeast Saccharomyces cerevisiae was initiated in the group with the SIF process (simultaneous isomerization and fermentation). This process allows total conversion of xylose, ...
Sustentabilidade energética do etanol de primeira geração no Brasil : uma releitura crítica de referenciais metodológicos
(Universidade Federal de São Carlos, 2017-02-01)
In the long run, all fossil energy, such as oil, natural gas, coal, and radioactive material, will run out. Within a horizon of one or two centuries, all energy must come from renewable sources. The concept of sustainable ...
Catalisadores de Co e Pt suportados em La2O3 e SiO2 aplicados na reforma a vapor do etanol
(Universidade Federal de São Carlos, 2015-03-24)
In intense search best environmental conditions, it is necessary to invest in renewable fuels, affordable and low polluting. With the aim to participate in this effort, this work was undertaken to study the steam reforming ...
Fermentação alcoólica: desenvolvimento de metodologia para o cálculo de eficiência e modelagem por redes neurais de unidade de fermentação industrial
(Universidade Federal de São Carlos, 2019-02-21)
The search for alternative sources of fuel, economically and environmentally viable, that could replace fossil fuels has increased in the last years. Brazil occupies a prominent position regarding the pioneering development ...
Modelagem, simulação e análise técnico-econômica-ambiental do processo de extração de óleo de soja por hexano e etanol e da produção de biodiesel
(Universidade Federal de São Carlos, 2019-07-04)
Brazil is the second largest producer of soybean, with the projection of becoming the largest producer in 2019/2020. All Brazilian soybean oil is produced by the extraction process with hexane, an oil derivative. One way ...
