Estudo do desempenho de eliminadores de névoa na fermentação alcoólica extrativa
(Universidade Federal de São Carlos, 2021-08-27)
The ethanol removal by gas stripping with CO2 offers a potential way to minimize the inhibitory effects of ethanol on yeast cells during the alcoholic fermentation, allowing higher ethanol volumetric productivity compared ...
Immobilization of enzymes of agroindustrial interest on hydroxyapatite nanoparticles: β-glucosidase, xylase and phytase
(Universidade Federal de São Carlos, 2020-03-10)
Industrial processes are increasingly requiring environmentally sustainable technologies and the use of enzymes is relevant due to the selectivity and specificity of these biocatalysts. However, the application of soluble ...
Niobium-based oxides for oxidative and reductive photocatalytic reactions
(Universidade Federal de São Carlos, 2020-02-21)
It is growing the number of studies related to alternative technologies allowing both, environmental remediation and clean energy production. In this sense, photocatalysis is a promising process, since it is sustainable ...
Combinação de óxidos mistos aplicados como catalisadores na reação de reforma seca do metano para produção de gás de síntese
(Universidade Federal de São Carlos, 2020-08-27)
Dry reforming of methane (DRM) is a promising process in synthetic gas generation with a low H2/CO ratio. The generation of syngas is of great industrial interest in a number of processes, in particular in the production ...
Desenvolvimento de metodologia para monitoramento contínuo da concentração de emissão de PM1 em fontes estacionárias industriais
(Universidade Federal de São Carlos, 2020-08-31)
Among the processes that generate emissions of ultrafine particles (UFP), which are known by their high potential to cause brain diseases when inhaled, the prilling towers have a significant contribution, as those processes ...
Rotas verdes para obtenção de nanocelulose em biorrefinarias: desenvolvimento de estratégias via hidrólise enzimática e com ácidos orgânicos
(Universidade Federal de São Carlos, 2020-05-29)
The growing demand for materials from sustainable sources with potential to replace petroleum-based polymers in technological applications projects lignocellulosic biomass as a promising raw material. In this context, ...
Compreendendo a reação ‘step-wise’ de conversão de metano a metanol usando zeólitas trocadas ionicamente com cobre
(Universidade Federal de São Carlos, 2020-03-06)
Methane (CH4) is a stable molecule abundantly found on our planet with reserves even
greater than crude oil. Due to its high availability and environmental impacts caused by
its emission into the atmosphere, the development ...
Hidrólise controlada das proteínas do leite de vaca com proteases imobilizadas para redução da alergenicidade
(Universidade Federal de São Carlos, 2020-09-29)
Allergy to cow's milk is clinically an abnormal reaction to cow's milk proteins regulated by immunological mechanisms and which affects mainly children. The partial hydrolysis of these proteins, catalyzed by proteases, ...
Estudo de MOFs zeolíticas de imidazolato com Zn(II) e Co(II) e emprego na condensação de Knoevenagel
(Universidade Federal de São Carlos, 2021-05-26)
A new segment of porous materials has emerged last years: metal organic frameworks (MOFs). Zeolitic imidazolate frameworks (ZIFs), a subclass of MOFs, are formed by metallic cations and imidazolates presenting similar ...
Aproveitamento de CO2 para a produção de metanol e compostos C2+ aplicando catalisadores à base de Cu e Fe
(Universidade Federal de São Carlos, 2021-08-10)
Considering the approaches to use of the CO2, this work aimed to study CO2 hydrogenation at gas phase and CO2 reduction (CO2RR) via electrocatalysis. Through these methodologies a wide variety of value-added products can ...
