Avaliação da fermentação alcoólica extrativa em diferentes temperaturas com remoção de etanol por arraste com CO2
(Universidade Federal de São Carlos, 2023-02-23)
By reducing the fermentation temperature, the inhibitory effect of ethanol is also reduced, resulting in wines with higher ethanol contents, but with a significant decrease in ethanol productivity, due to the negative ...
Síntese de ésteres graxos de açúcar catalisada por derivados imobilizados-estabilizados de candida antarctica lipase B
(Universidade Federal de São Carlos, 2023-03-21)
The biotechnology industry is increasingly seeking to deploy high productivity and stable biocatalysts for commercial-scale production of bioproducts. In addition, with global warming, enzyme-based production systems using ...
Borra de café: análise da caracterização termoquímica, do processo de elutriação, secagem, peletização e da mistura com outros resíduos
(Universidade Federal de São Carlos, 2023-04-27)
For the reuse of the spent coffee grounds, this thesis has two main strategies, the first is to evaluate its granulometry as a function of the thermal degradation behavior, the elutriation, drying process, pelletization ...
Desenvolvimento e estudo da influência de um modelo de força de lubrificação em um leito fluidizado líquido utilizando CFD-DEM não resolvido
(Universidade Federal de São Carlos, 2023-02-28)
Solid-fluid multiphase flows are common occurrences in chemical engineering applications. Due to the scale and unpredictability of the fundamental phenomena in these systems, microscopic interactions between individual ...
Secagem convectiva de concentrado de minério de ferro: abordagem experimental e simulações por fluidodinâmica computacional
(Universidade Federal de São Carlos, 2023-02-27)
Conventional transfer chutes are equipment used to change the solids flow direction in transporting systems that use conveyor belts. During operation, the solid transported by the upper conveyor belt enters the chute and ...
Produção de celulases por Myceliophthora thermophila I-1D3b em resposta a diferentes fontes de carbono e taxas de aeração em cultivos sólido e submerso
(Universidade Federal de São Carlos, 2023-02-24)
The interest in cellulolytic systems of thermophilic fungi motivated the development of research aimed at the use of their enzymes in various industrial sectors, such as in the production of biofuels, particularly ...
High-performance chloride-doped polyaniline activated carbon modified with PluronicTM template for electrochemical desalination
(Universidade Federal de São Carlos, 2023-02-15)
Activated carbon obtained from chloride-doped polyaniline (PAC/Cl) is an attractive material for brackish water desalination using capacitive deionization (CDI), due to its easy synthesis, low cost, and fast electrosorption ...
Design of new immobilized lipases for biotransformations in aqueous and organic media
(Universidade Federal de São Carlos, 2023-01-30)
A review of the literature covering research on the immobilization of lipases on hydrophobic supports was performed using systematic mapping (MS) concepts. The MS approach enabled the identification of gaps that led to the ...
Avaliação experimental e computacional da eficiência de separadores ciclônicos aplicados na coleta e concentração do minério de ferro proveniente de secagem convectiva
(Universidade Federal de São Carlos, 2023-02-24)
Iron is closely related to the development of a country, being a key element in the production of various goods for daily use. One of the fundamental stages in its processing is the moisture content control. In this sense, ...
Método da quadratura de momentos aplicado à simulação da distribuição de tamanho de bolhas em um biorreator pneumático por CFD
(Universidade Federal de São Carlos, 2023-02-24)
Aeration is crucial for the functioning of pneumatic bioreactors, as injecting gas into the system allows to perform agitation of the medium and as well as to improve mass transfer with lower energy consumption. Bubble ...
