Análise térmica da fermentação alcoólica convencional e extrativa com arraste por dióxido de carbono
(Universidade Federal de São Carlos, 2020-02-18)
Extractive fed-batch ethanol fermentation using carbon dioxide (CO2) as striping gas has several advantages compared to the conventional fermentation, such as: reducing the effect of ethanol inhibition, allowing to use ...
Avaliação da secagem convectiva de resíduos da indústria cervejeira
(Universidade Federal de São Carlos, 2020-03-05)
Brazil is the third largest beer producer in the world, with an estimated production of 14.1 billion liters of the product for the year 2018, generating several co-products throughout the process, being brewer’s spent grain ...
Modelagem e simulação da produção de biossurfactante em biorrefinaria integrada biodiesel-bioetanol
(Universidade Federal de São Carlos, 2020-03-02)
Biosurfactants are amphipathic molecules produced by enzymatic or microbiological routes. Biosynthesis can occur by esterifying sugars with fatty acids, with lipase as the main enzyme that catalyzes the reaction. However, ...
Síntese de hidróxido duplo lamelar: efeitos do processo de secagem
(Universidade Federal de São Carlos, 2020-02-20)
Because of its chemical versatility, ionic exchange and regeneration capacity, Layered Double Hydroxides (LDHs), have recently been recognized as a promising material due to their many application areas. Drying is an ...
Avaliação técnica da gaseificação do bagaço de cana-de-açúcar em reator contínuo de leito fluidizado
(Universidade Federal de São Carlos, 2020-02-19)
The sugar and alcohol sector introduces a big potential to expand the production lines of ethanol, sugar and clean electric energy with a profitable harnessing of its residues and sub products, like sugar cane bagasse. The ...
Solubilização biológica de rocha potássica para aplicação como biofertilizante
(Universidade Federal de São Carlos, 2020-02-18)
Potassium (K) plays an important role in several biochemical and physiological processes in plants, but the low concentrations of soluble K in the soil make it necessary to use chemical fertilizers in order to supply the ...
Monitoramento da hidrólise enzimática de bagaço de cana-de-açúcar por métodos espectrofotométricos
(Universidade Federal de São Carlos, 2020-02-23)
The production process of 2nd generation ethanol (2G), using sugarcane bagasse, is a promising way to increase ethanol production without increasing the cultivation area. However, the process has been studied to become ...
