Análise do efeito das condições operacionais e características geométricas do leito de jorro na secagem de pastas
(Universidade Federal de São Carlos, 2015-07-06)
In this present work, the fluidynamic and drying process of paste in a spouted
bed was analyzed. The experiments were conducted using polyethylene particles of 4.38 mm
of diameter and 930.5 ± 0.3 kg/m3 of specific mass ...
Síntese de adsorventes magnéticos utilizando casca de soja e sua aplicação na adsorção de ácido cafeico
(Universidade Federal de São Carlos, 2018-12-11)
Wastewater management has gained increasingly space on the world stage, with significant advances in both the environmental and financial spheres. Phenolic compounds are present in wastewater of various processes, such as ...
Modelagem, simulação e análise técnico-econômica-ambiental do processo de extração de óleo de soja por hexano e etanol e da produção de biodiesel
(Universidade Federal de São Carlos, 2019-07-04)
Brazil is the second largest producer of soybean, with the projection of becoming the largest producer in 2019/2020. All Brazilian soybean oil is produced by the extraction process with hexane, an oil derivative. One way ...
Particle image velocimetry and computational fluid dynamics applied to study the effect of hydrodynamics forces on animal cells cultivated in Taylor vortex bioreactor
(Universidade Federal de São Carlos, 2016-03-28)
Taylor-Vortex reactor (TVB) is fast becoming the next bioreactor to culture animal cells due to milder shear and homogeneous flow structures through-out the bioreactor in comparison to the traditional stirred vessels. ...
Partículas rugosas de sílica híbrida aplicadas na transesterificação catalítica
(Universidade Federal de São Carlos, 2019-03-15)
Heterogeneous catalysts are potentially responsible for reducing the cost of producing biodiesel, due to its reusability or use in continuous process. As-synthesized hybrid silicas, containing siloxy sites, can be used as ...
Catalisadores magnéticos à base de ferritas de Co ou Zn e de heteroestruturas TiO2/Ferrita – Avaliação na degradação fotocatalítica de lignina
(Universidade Federal de São Carlos, 2018-05-30)
Vinasse derived from beverage industry represents a serious environmental risk if not properly treated, mainly attributable to the presence of organic macromolecules with complex structure and composition, the recalcitrant ...
Catalisadores Pt/Al2O3 e CeO2/Pt/Al2O3 aplicados à reação deslocamento gás-água: efeito da composição nas propriedades estruturais e catalíticas
(Universidade Federal de São Carlos, 2018-08-17)
Alumina-supported platinum catalysts were synthesized via conventional impregnation varying the metal contents (0.3 to 2% Pt; 6 to 20% Ce, m / m) and the Pt precursors (H2PtCl6 and [Pt(NH3)4] (NO3)2), were evaluated for ...
Avaliação da produção de açúcar utilizando reconciliação de dados, estatística multivariada e modelagem fenomenológica da cristalização
(Universidade Federal de São Carlos, 2019-02-25)
Sugarcane, grown in more than a hundred countries, is one of the major crops of the world. Brazil is the world’s largest producer. Sugarcane industries are constantly seeking to reduce the industrial process losses, to ...
Catalisadores Ni-Fe/MgAl2O4 na reforma a vapor do etanol: influência da razão molar Ni/Fe nas propriedades catalíticas
(Universidade Federal de São Carlos, 2017-03-02)
The effect of iron incorporation on the catalytic properties of Ni / MgAl2O4 for the Ethanol Steam Reforming (ESR) was studied. Samples of different Fe/Ni molar ratios were prepared by wet impregnation of MgAl2O4, synthesized ...
Análise do material particulado na área central da cidade de São Carlos-SP através de técnicas espectroanalíticas e avaliação multidimensional de séries temporais
(Universidade Federal de São Carlos, 2019-05-23)
Due to the worldwide trend of industrialization and urbanization, air pollutants are emitted large
quantities on a global scale, particularly in developing countries, which produces adverse
effects on human health by ...
