Lipase “whole-cell” de Streptomyces clavuligerus : produção, caracterização e aplicação em meio orgânico
(Universidade Federal de São Carlos, 2016-08-25)
Cell-associated lipases have been considered biocatalysts economically advantageous because
they are produced at low cost, avoiding further recovery or purification steps. Few studies
regarding Streptomyces clavuligerus ...

(Universidade Federal de São Carlos, 2015-08-27)
The genus Salmonella spp. has been extensively investigated because these
bacteria are important pathogens that frequently cause severe diseases and gastrointestinal
infections in humans and animals. Moreover, in recent ...
Oxidação de CO sobre catalisadores de Co e/ou Mn modificados com Mo e suportados em SBA-15 – Efeito do método de preparação e da presença de vapor de água e dióxido de enxofre na atividade catalítica
(Universidade Federal de São Carlos, 2016-08-25)
The increasing demand for oil and oil derived products contributed to the alarming increase in the gaseous pollutants emissions in general and mainly contributed to the increase in carbon monoxide (CO) emissions in the ...
Aplicação de técnicas de Fluidodinâmica Computacional (CFD) na avaliação da hidrodinâmica e da transferência de massa em estágio de coluna de destilação
(Universidade Federal de São Carlos, 2015-02-19)
Distillation is one of the most important industrial separation techniques. It requires high quantity of energy, corresponding to around 40% of the total energy consumption of chemical industries. As such, the optimization ...

(Universidade Federal de São Carlos, 2015-08-27)
The black pepper is the most important spice commercialized globally, with Brazil being one of the main producers in the world. Yet few studies to optimize the production of this commodity process have been found in the ...
Síntese da zeólita Beta usando planejamento experimental e emprego na isomerização do n-hexano
(Universidade Federal de São Carlos, 2012-09-14)
This work aimed to apply the Design Of Experiment (DOE) methodology as an auxiliary tool to evaluate the conditions of synthesis of the aluminum-rich zeolite Beta. Bimetallic catalysts with 50% platinum and 50% nickel ...
Reações cíclicas de oxidação e redução de materiais a base de Ni para geração de hidrogênio
(Universidade Federal de São Carlos, 2017-04-06)
Hydrogen (H2) is used in several industrial processes, including ammonia production and petroleum refining. Commercially, most of the H2 produced is from methane steam reforming. Although well established industrially, ...
Catalisadores de CuO, Fe2O3 ou Co3O4 suportados em TiO2, CeO2 ou ZrO2: preparação via Sol-gel in situ ou impregnação e avaliação na redução de NO com CO
(Universidade Federal de São Carlos, 2012-04-13)
The minimization of the emissions of nitrogen oxides (NOx) is a subject of crucial interest, since them cause serious environmental problems which affect human health, vegetation and fauna. With the purpose to abate NOx, ...
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 ...
