Influência da concentração de H2O2 na síntese de Nb2O5 com atividade fotocatalítica sob luz visível
(Universidade Federal de São Carlos, 2019-02-22)
Heterogeneous photocatalysis is a technology that can be used for the treatment of wastewater and one of the interesting aspects of this technique is the possibility of using visible light (solar) to activate the photocatalyst. ...
Efeito do tamanho de partículas de Cu nas propriedades estruturais e eletrônicas e suas correlações com propriedades catalíticas na desidrogenação do etanol em Cu/SiO2
(Universidade Federal de São Carlos, 2019-03-08)
Metal nanoparticles may exhibit distinct catalytic behavior when there are particle size variations at nanometric scale. Cu nanoparticles supported on SiO2 and CAB-O-SIL® were synthesized with different metal loadings by ...
Estudo cinético da hidrólise de xilooligômeros por xilanases e beta-xilosidase na forma livre e imobilizada
(Universidade Federal de São Carlos, 2018-03-15)
This work aims to contribute to the development of the ethanol production process from xylooligomers (XO) extracted from sugarcane bagasse hemicellulose through the hydrolysis of XO to xylose, xylose isomerization catalyzed ...
Avaliação da transferência de calor em fermentações alcoólicas convencional e extrativa
(Universidade Federal de São Carlos, 2019-02-26)
The inhibitory effect of ethanol on yeast and the temperature rise during the fermentation are the major drawbacks of the conventional ethanol production process. The use of extractive alcoholic fermentation with CO2 ...
Oxidação de CO sobre nanoestruturas controladas e de interiores vazios de AgPt dispersas em óxidos
(Universidade Federal de São Carlos, 2016-03-10)
The CO oxidation is considered one of the most studied reactions in heterogeneous catalysis. Although several studies have been developed in this field, the impact of some properties of catalysts, such as the oxygen mobility, ...
Caracterização de meios filtrantes através do estudo das normas de padronização de testes europeia e americana
(Universidade Federal de São Carlos, 2018-03-02)
Nowadays, people spend considerable part of their time indoors with air conditioners on. Even at work, in a car or at home, they expose themselves to what is known as indoor air pollution. The market offers a variety of ...
Propriedades da zeólita y contendo mesoporos formados por ação do surfactante CTA+
(Universidade Federal de São Carlos, 2018-02-22)
Zeolites are microporous, crystalline aluminosilicates that have numerous advantages due to their intrinsic properties such as acidity, hydrothermal stability and shape selectivity. However, the presence of micropores ...
Soybean biorefinery with residues exploitation : process assessment
(Universidade Federal de São Carlos, 2016-06-27)
Soybean seed is a renewable feedstock and the production process of soybean meal and
soybean refined oil generates residues that can be exploited, in such a way that the biorefinery
concept can be applied to this production ...
Desenvolvimento de reator eletroquímico de leito particulado para processo hidrometalúrgico de produção de cobre
(Universidade Federal de São Carlos, 2014-08-22)
Typical hydrometallurgical processes for metal production such as zinc, copper, nickel and cobalt, among others, are carried out in huge electrochemical tankhouses since only low current densities can be applied in order ...
Biorrefinaria florestal : uma proposta para integração dos processos de obtenção de nanocelulose e etanol 2G a partir da polpa de celulose de eucalipto
(Universidade Federal de São Carlos, 2016-02-29)
The use of eucalyptus kraft as biomass for an integrated production of sugars and new
added-value products such as nanocellulose, stands out a potential strategy for the
implementation of a forest biorefinary, that can ...
