Avaliação de modelos matemáticos para a simulação do escoamento água – ar na flotação por ar dissolvido utilizando fluidodinâmica computacional
(Universidade Federal de São Carlos, 2018-02-21)
The concern with the future of water on the planet has increased in past years, mainly due to the recent water crisis suffered throughout the country. The dissolved air flotation (DAF) operation is an example of the ...
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 ...
Aspectos morfológicos, reológicos e fisiológicos dos cultivos de Escherichia coli recombinante
(Universidade Federal de São Carlos, 2015-04-30)
The use of Escherichia coli cultures to obtain heterologous proteins poses as a successful application of biotechnology for the production of drugs and enzymes. However, the stress caused by the synthesis of the recombinant ...
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) ...
Compreendendo a reação ‘step-wise’ de conversão de metano a metanol usando zeólitas trocadas ionicamente com cobre
(Universidade Federal de São Carlos, 2020-03-06)
Methane (CH4) is a stable molecule abundantly found on our planet with reserves even
greater than crude oil. Due to its high availability and environmental impacts caused by
its emission into the atmosphere, the development ...
