Otimização da produção de ácido 3-hidroxipropiônico por Escherichia coli via engenharia metabólica e de processos
(Universidade Federal de São Carlos, 2022-10-14)
The integration of substrates from bioprocesses is of great interest due to the need of destination
for them and the possibility of converting them into value-added products. Among these
substrates, the hydrolysates ...
Produção enzimática de compostos de valor agregado a partir do destilado da desodorização do óleo de soja
(Universidade Federal de São Carlos, 2021-08-27)
The use of by-products (or residues) is sought in an industrial process in order to transform them into a value-added product. In the soybean oil refining industry, deodorization distillate (SODD) is a by-product with great ...
Synthesis of isoamyl esters from soybean oil deodorizer distillate by enzymatic catalysis for biolubricant applications
(Universidade Federal de São Carlos, 2022-07-26)
Lubricants are among the many products whose manufacture is highly dependent on nonrenewable fossil resources, with high levels of production and a vast marketplace, so they are the focus of many environmental laws around ...
Produção integrada de etanol de cana-de-açúcar e milho em usinas flex: simulação e análises tecno-econômica e ambiental
(Universidade Federal de São Carlos, 2022-03-03)
Liquid biofuels are important alternatives to traditional fossil fuels, not only environmentally, but also socially and from an energy security standpoint. Brazil has a consolidated infrastructure for the production, ...
Rational design and engineering of a microbial cell factory for 3-hydroxypropionic acid production
(Universidade Federal de São Carlos, 2021-04-20)
The US Department of Energy ranked the 3-hydroxypropionic acid (3-HP) among the Top 10 most promising value-added chemicals that can be derived from biomass in a biorefinery. This acid has great potential to serve as a ...
Conversão de furfural sobre zeólitas (Hf, Al)-ZSM-5 hierárquicas: controle da relação de sítios ácidos de Lewis e Brønsted e seu efeito na seletividade a produtos
(Universidade Federal de São Carlos, 2021-04-29)
One-pot catalytic processes using heterogeneous acid catalysts have been a promising strategy for the valorization of platform molecules from lignocellulosic biomass, such as the transformation of furfural (Fur) to ...
Estudo da secagem da polpa do abacate (Persea americana)
(Universidade Federal de São Carlos, 2021-04-26)
The drying process can be carried out by different methods, but the choice directly influences the quality of the final product, which can obviously be affected by operational conditions. This work aims to study the drying ...
Fluidodinâmica e transferência de calor em leitos de jorro visando a secagem de grãos de Sorgo: análise experimental e simulação numérica por CFD-DEM e TFM
(Universidade Federal de São Carlos, 2021-04-23)
Simulations of granular flows in spouted beds are carried out following two main approaches: two-fluid model (TFM) and CFD-DEM coupling (Computational Fluid Dynamics/Discrete Element Method). Moreover, the fluid dynamics ...
Análise da viabilidade técnica e econômica da integração do processo de recuperação de etanol por arraste (stripping) com CO2 na indústria sucroenergética
(Universidade Federal de São Carlos, 2021-04-29)
Brazil is the world's largest sugarcane ethanol producer which puts the country in a stand-out position among the bioenergy producers. Ethanol is an important biofuel in the renewable energy matrix. In 2017, the Brazilian ...
Catalisadores de Cr/ZrO2 promovidos com metais alcalinos ou alcalinos terrosos para a desidrogenação oxidativa do propano com CO2
(Universidade Federal de São Carlos, 2021-04-27)
Propene is used as a raw material for thermoplastic resins, adhesives and acrylic derivatives, being obtained mainly by steam cracking naphtha and natural gas. However, the oxidative dehydrogenation of propane reaction ...
