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 com estrutura do tipo perovskitas PrCo1-xNixO3 para produção de gás de síntese
(Universidade Federal de São Carlos, 2017-03-14)
Energy is an essential component for a country's development. Since Brazilians’ main energy source is the oil and it has limited reserves, an alternative is needed for a synthesis of fuels throughout other raw materials, ...
Produção de etanol 2G a partir de hemicelulose de bagaço de cana-de-açúcar utilizando Saccharomyces cerevisiae selvagem e geneticamente modificada imobilizadas
(Universidade Federal de São Carlos, 2017-03-30)
In ethanol production process from hemicellulosic fraction, the use of xylooligomers (XOS)
as substrate reduce the contamination risk, favoring its application at industrial scale. Thus, a
biocatalyst, containing xylanases, ...
Produção de hidrogênio e metano a patir de glicerol bruto e cultura mista em reatores anaeróbios de leito fluidizado termofílicos
(Universidade Federal de São Carlos, 2017-03-24)
The study aimed to evaluate the continuous production of hydrogen and methane under
thermophilic conditions (55 °C) using crude glycerol as substrate and mixed culture. The first
study aimed at the production of H2, and ...
Catalisadores de Au suportados aplicados à oxidação preferencial do CO : influência da interação entre Au e Fe nos sítios ativos
(Universidade Federal de São Carlos, 2017-04-07)
New sources of clean energy have been studied, such as hydrogen (H2). Carbon monoxide, a subproduct of its production, poisons the fuel cell. To reach concentrations below 10 ppm, the addition of preferential CO oxidation ...
Engenharia de biocatalisadores aplicada à síntese de CLEAs para a aplicação na conversão multienzimática de sacarose à ácido glucônico e xarope de frutose
(Universidade Federal de São Carlos, 2017-02-17)
Sugarcane sugar (sucrose) is a raw material produced in abundance in Brazil; it is very attractive to produce high added-value products. Gluconic acid (GA) can be obtained by multienzymatic conversion of sucrose, using ...
