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 ...
Catalisadores derivados de óxidos do tipo perovskita LaMO3, LaMFeO3 e LaMO3/γ-Al2O3 (M = Co, Ni ou Fe) aplicados à reforma a vapor de etanol
(Universidade Federal de São Carlos, 2014-07-30)
The hydrogen production has been extensively studied as a clean and powerful energy source, indicating that in the future hydrogen will became a key component for the global energy production, since burning fossil fuels, ...
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 ...
Pré-tratamento alcalino (NaOH) do bagaço de cana-de açúcar para a produção de etanol e obtenção de xilooligômeros
(Universidade Federal de São Carlos, 2011-03-28)
The aim of this study was to optimize the pretreatment of sugarcane bagasse raw and exploded with diluted sulfuric acid, water and sodium hydroxide in order to obtain Xylooligosaccharides in hemicellulose and production ...
Influência da linhagem da levedura e das condições de cultivo no processo de isomerização e fermentação simultâneas da xilose
(Universidade Federal de São Carlos, 2013-03-21)
The conversion of the hemicellulosic fraction in ethanol is a factor that impacts on the economic viability of the second generation ethanol production process from sugar cane bagasse. Hemicellulose from bagasse is a ...
Estratégias de melhoria do bioprocesso de produção de enzimas celulolíticas por Aspergillus niger a partir de bagaço de cana-de-açúcar para a produção de etanol de segunda geração
(Universidade Federal de São Carlos, 2015-03-05)
The second generation ethanol (2G) production from sugarcane bagasse is a promising
strategy to increase ethanol production per hectare. The 2G ethanol production comprises the steps of biomass pretreatment, hydrolysis ...
Perovskitas do tipo LaNixCo1-xO3 suportadas em SBA-15 como precursores de catalisadores Ni-Co aplicados à reforma a vapor do etanol
(Universidade Federal de São Carlos, 2018-04-19)
The production of hydrogen from the steam reforming process of ethanol stands out as
a process for the diversification of the world energy matrix, which aims to reduce environmental
impacts and ensure energy security. ...
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, ...
