Produção de enzimas pelo cocultivo de fungos filamentosos por fermentação em estado sólido e aplicação do meio integral na sacarificação da biomassa para obtenção de etanol celulósico
(Universidade Federal de São Carlos, 2016-03-01)
The use of a simplified consolidated bioprocess for the conversion of biomass using
enzymes produced in-house (integrated into the process of converting lignocellulosic
biomass) may enable significant increases in the ...
Metodologia para guiar o desenvolvimento e implementação industrial de novas tecnologias unindo engenharia econômica e Engenharia de (bio)processos e sistemas : aplicação à produção de etanol de segunda geração
(Universidade Federal de São Carlos, 2016-03-18)
Lignocellulosic ethanol, also called second generation ethanol, is a promising alternative for decreasing fossil fuel dependency globally. Nevertheless, its production process still needs further improvements in order to ...
Estudos de melhorias no processo de hidrólise enzimática de biomassas para produção de etanol
(Universidade Federal de São Carlos, 2016-02-04)
In this work it was evaluated, firstly, the performance of four impellers configurations in the enzymatic hydrolysis of sugarcane bagasse. The configurations evaluated were: (1): Rushton turbine - Rushton turbine; (2): ...
Aplicação de biorreatores anaeróbios em diferentes temperaturas para produção de hidrogênio a partir de águas residuárias agroindustriais
(Universidade Federal de São Carlos, 2016-03-18)
The present evaluated the influence of hydraulic retention time (HRT), cheese whey substrate
concentration, temperature in thermophilic range (55 a 75oC) and cofermentation of sugar
cane stillage and cheese whey in ...
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 ...
Secagem de materiais têxteis
(Universidade Federal de São Carlos, 2016-04-08)
The fabrics are derived from fibers, which are divided into to main groups: natural (like cotton) and chemical (such as rayon and polyester). In the processing of the fabric, drying is a major operation, contributing to ...
Cristalização da sacarose : estudos experimentais, modelagem matemática e influência de impurezas
(Universidade Federal de São Carlos, 2016-02-29)
Sugarcane is one of the main Brazilian crops. Studies encompassing unit operations of its industrial processes are old and broad in literature. However, the industrial process itself has changed very slowly over the years, ...
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 ...
Análise da dinâmica de secagem de pasta em leito de jorro
(Universidade Federal de São Carlos, 2016-02-22)
Although there are several mathematical models in the literature used for paste drying in spouted beds, few of them have focused on transient analysis of dynamic system. Therefore, the purpose of this study was to integrate ...
Dinâmica, otimização e controle de processos de fermentação em estado sólido : desenvolvimento de metodologias em escala laboratorial
(Universidade Federal de São Carlos, 2016-05-04)
Solid-state fermentation is characterized by the growth of microorganisms in absence of free
water. In one hand, it is advantageous because simulates their natural environment, enabling
the use of agro industrial residues ...
