Transesterificação de ésteres etílicos e estudo cinético usando a sílica CTA-MCM-41
(Universidade Federal de São Carlos, 2020-02-28)
The synthesis of biodiesel, through transesterification, occurs industrially in the presence of basic homogeneous catalysts, where others steps are necessary, such as washing and neutralization of the final product due to ...
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 ...
Síntese de compostos C2+ a partir de CO2 e H2O aplicando materiais de Cu e Cu-Zn: estudos na catálise heterogênea em fase gasosa e eletrocatálise
(Universidade Federal de São Carlos, 2020-08-25)
Strategies aimed at recycling of CO2 in producing chemicals and fuels are needed to reduce the environmental impacts caused by this gas and attend the industrial interests. Among the all applied strategies, we highlight ...
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 ...
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, ...
Modelagem cinética da síntese de galacto-oligossacarídeos usando a β-galactosidase de Kluyveromyces lactis
(Universidade Federal de São Carlos, 2020-12-22)
Galacto-oligosaccharides (GOS) have a high commercial value and are used in the food industry. GOS are non-digestible oligosaccharides (NDO), which are considered prebiotics. They can be produced enzymatically from substrates ...
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, ...
Compósitos reticulados de Eversa® Transform e nanopartículas magnéticas como biocatalisadores para a síntese de biodiesel em reator de fluxo em vórtices
(Universidade Federal de São Carlos, 2020-10-30)
The enzymatic production of biodiesel is a promising alternative to the conventional production
by the alkaline route in a homogeneous medium. The enzymatic process allows using raw
material with any concentration of ...
Catalisadores de CuO/CeO2 promovidos com Au e Pt - estudo do impacto da interface e das propriedades eletrônicas do Cu no desempenho catalítico na reação de CO-PROX
(Universidade Federal de São Carlos, 2020-05-06)
The copper-ceria system has been extensively investigated to be used as a catalyst in the preferential oxidation of CO reaction (CO-PROX), aiming the purification of H2 streams from reformed fuels, due to its oxygen storage ...
