Estudo do processo integrado de fermentação alcoólica extrativa com CO2 com desidratação por adsorção e recuperação por absorção
(Universidade Federal de São Carlos, 2022-06-30)
To minimize the effects of ethanol inhibition, increase productivity, and reduce energy and environmental footprint, different strategies of ethanol removal by gas stripping with CO2 during alcoholic fermentation have been ...
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 ...
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 ...
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, ...
O efeito do potássio (K) na formação de CH4 na reação de reforma a vapor e sua relação com a estrutura da molécula reformada
(Universidade Federal de São Carlos, 2021-10-29)
Nickel (Ni) catalysts were applied in the steam reforming reaction of organic compounds. Ni is highly active for breaking C-C bonds, a route in steam reforming reactions to generate hydrogen (and CO), however it is also ...
