Avaliação de adsorventes obtidos a partir de resíduos agroindustriais para a remoção dos inibidores gerados no pré-tratamento da biomassa lignocelulósica
(Universidade Federal de São Carlos, 2019-02-26)
The pretreatment of lignocellulosic biomass generates phenolic compounds and furaldehydes that inhibit the enzymes and yeast used in the process of hydrolysis of cellulose and alcoholic fermentation. In this context, the ...
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. ...
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 ...
Estudo da produção de bioetanol e biobutanol a partir da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2019-02-18)
The present thesis studied the hydrolysis and fermentation steps of the hydrothermally pretreated sugarcane straw (cellulosic fraction), aiming bioethanol and biobutanol production. In regards to the hydrolysis step, it ...
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 ...
Modificação de meios filtrantes com nanomateriais para controle de bioaerossóis
(Universidade Federal de São Carlos, 2018-06-15)
People are increasingly wasting their time in indoors environments, in these locations there is a risk of contagion from diseases transmitted by the airways, due to low rates of air exchange. Thus, the number of causative ...
Modelagem e simulação de aspectos hidrodinâmicos e cinéticos do processo de gaseificação de biomassa utilizando CFD
(Universidade Federal de São Carlos, 2017-06-28)
One of the major problems faced by humanity nowadays is the issue of preserving the environment. In recent years, progress has been accelerated, having a direct influence on the environmental impacts caused by several kinds ...
Desenvolvimento e avaliação de meios filtrantes com nanofibras eletrofiadas e agentes bactericidas aplicados na filtração de ar
(Universidade Federal de São Carlos, 2019-03-29)
Filtration processes using fibrous filter media are very used to retain microparticles in a stream air due to its simple use, low operational cost and high collection efficiency. However, the study of submicron particles ...
Avaliação do desempenho do biorreator de vórtices de Taylor na expansão de células estromais mesenquimais
(Universidade Federal de São Carlos, 2019-04-29)
Interest in the use of mesenchymal stromal cells (MSCs) has increased in the last 10 years because of the increasing discovery of its special characteristics for the treatment of diseases through cell therapy or tissue ...
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 ...
