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 ...
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. ...
Preparação e caracterização do catalisador óxido misto de cobre-zinco-alumínio, obtido via complexação (processo citrato), para a transformação do etanol a acetato de etila
(Universidade Federal de São Carlos, 1991-07-02)
Cu-Zn-Al mixture oxides catalysts with atomic ratios r-Cu/Zn=3,0 and R=Cu+Zn/Al=1,2 were obtained by means of citric complexing method. The influence of citric acid content was studied varying P=(eq.citric acid/Eq.metal) ...
Produção otimizada de 1,3-propanodiol, ácido propiônico, etanol e hidrogênio, a partir de glicerol bruto e cultura mista, em reator anaeróbio de leito fluidificado
(Universidade Federal de São Carlos, 2016-03-18)
This study aimed to optimize the production of hydrogen and other metabolites using
crude glycerol as substrate, through design of experiments (DoE) and statistical process
optimization. The first study aimed at optimizing ...
Separação adsortiva de misturas etanol-água por processo PSA.
(Universidade Federal de São Carlos, 2005-03-02)
The ethanol is one of the most well-known and diffused fuels sources in
nowadays, therefore the domain of its technology has a great importance to the producer
countries. Beyond it is in general, lesser expensive than the ...
A influência da morfologia do MgO nas propriedades catalíticas do SiO2/MgO para a formação de 1,3-Butadieno a partir de etanol
(Universidade Federal de São Carlos, 2016-05-31)
Ethanol has been largely studied in the past few decades as a substitute to fossil fuels
in the synthesis of a large variety of chemicals. 1,3-Butadiene, one of these compounds, is an important chemical intermediate and ...
Efeito da velocidade ascensional na produção de hidrogênio em reator anaeróbio de leito fluidizado
(Universidade Federal de São Carlos, 2010-08-30)
This study evaluated the influence of the upflow velocity in anaerobic fluidized bed reactor to produce hydrogen. In order to compare that effect, four reactors were used under different upflow velocities each: 0.30; 0.60; ...
Produção integrada de etanol de cana-de-açúcar e milho em usinas flex: simulação e análises tecno-econômica e ambiental
(Universidade Federal de São Carlos, 2022-03-03)
Liquid biofuels are important alternatives to traditional fossil fuels, not only environmentally, but also socially and from an energy security standpoint. Brazil has a consolidated infrastructure for the production, ...
