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 ...
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 ...

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 ...
Análise técnico-econômica-ambiental da produção de nanocelulose em biorrefinarias de cana-de-açúcar
(Universidade Federal de São Carlos, 2021-08-31)
The production of ethanol, sugar and energy in Brazilian sugarcane biorefineries
generates a large number of residues, such as bagasse and straw. An alternative is the
reuse of these residues as feedstock for obtaining ...
Cellulose nanomaterials isolated via enzymatic and mechanical routes for application in hydrogels
(Universidade Federal de São Carlos, 2021-11-10)
The integrated production of different bioproducts has been considered essential to make biorefineries economically viable. Among the bioproducts, cellulose nanomaterials (CNs) have attracted significant attention due to ...

(Universidade Federal de São Carlos, 2021-07-29)
Air pollution and solid pollution are considered global problems, and endanger human health mainly due to the improper disposal of solid wastes, as the post-consumer plastic botlles.. The filtration process using fibrous ...
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 ...
Intermittent drying and draft tube design for spouted bed
(Universidade Federal de São Carlos, 2021-12-08)
The conventional spouted bed has presented several limitations that restrict the use on an industrial scale. Thus, studies of different methodologies and configurations have been performed to overcome such limitations. ...
O efeito do potássio (K) na formação de CH4 na reação de reforma a vapor e sua relação com a estrutura da molécula reformada
(Universidade Federal de São Carlos, 2021-10-29)
Nickel (Ni) catalysts were applied in the steam reforming reaction of organic compounds. Ni is highly active for breaking C-C bonds, a route in steam reforming reactions to generate hydrogen (and CO), however it is also ...
