Fotoconversão de CO2 em produtos com valor agregado
(Universidade Federal de São Carlos, 2021-04-29)
In recent decades, due to population and industrial growth, the energy demand has increased significantly. However, much of the energy consumed comes from burning fossil fuels, which emit large amounts of gases that can ...
Conversão de furfural sobre zeólitas (Hf, Al)-ZSM-5 hierárquicas: controle da relação de sítios ácidos de Lewis e Brønsted e seu efeito na seletividade a produtos
(Universidade Federal de São Carlos, 2021-04-29)
One-pot catalytic processes using heterogeneous acid catalysts have been a promising strategy for the valorization of platform molecules from lignocellulosic biomass, such as the transformation of furfural (Fur) to ...
Análise técnico-econômica-ambiental da produção de nanocelulose em biorrefinarias de cana-de-açúcar
(Universidade Federal de São Carlos, 2021-08-31)
The production of ethanol, sugar and energy in Brazilian sugarcane biorefineries
generates a large number of residues, such as bagasse and straw. An alternative is the
reuse of these residues as feedstock for obtaining ...
Cellulose nanomaterials isolated via enzymatic and mechanical routes for application in hydrogels
(Universidade Federal de São Carlos, 2021-11-10)
The integrated production of different bioproducts has been considered essential to make biorefineries economically viable. Among the bioproducts, cellulose nanomaterials (CNs) have attracted significant attention due to ...
Modelagem matemática para sínteses enzimáticas de biossurfactantes catalisadas por lipases imobilizadas
(Universidade Federal de São Carlos, 2021-07-08)
Enzymatic reactions of esterification of fatty acids with carbohydrates generate biosurfactants, products with high capacity to reduce surface and interfacial tensions, applicable mainly in the food, pharmaceutical and ...
Oxidação direta de metano a metanol sobre espécies [CuxOy] incorporadas em zeólitas ferrierita
(Universidade Federal de São Carlos, 2021-05-06)
The development of technologies to minimize the CO2 emissions, which are generated by the indiscriminate burning of fossil fuels, remains a relevant research topic in the context of the planet's sustainability. Thus, it ...
Produção de meios filtrantes a partir de garrafas PET recicladas para aplicações em filtração de ar com alta eficiência de coleta de nanopartículas através da técnica de Electrospinning
(Universidade Federal de São Carlos, 2021-07-29)
Air pollution and solid pollution are considered global problems, and endanger human health mainly due to the improper disposal of solid wastes, as the post-consumer plastic botlles.. The filtration process using fibrous ...
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 ...
Catalisadores de Cr/ZrO2 promovidos com metais alcalinos ou alcalinos terrosos para a desidrogenação oxidativa do propano com CO2
(Universidade Federal de São Carlos, 2021-04-27)
Propene is used as a raw material for thermoplastic resins, adhesives and acrylic derivatives, being obtained mainly by steam cracking naphtha and natural gas. However, the oxidative dehydrogenation of propane reaction ...
Catalisadores Ni/SBA-15 com adição dos promotores aplicados a tri reforma do metano
(Universidade Federal de São Carlos, 2021-10-27)
Tri-reforming of methane (TRM) is a combination of steam and dry reforming and partial oxidation of methane reactions in the same reactor. Since it occurs at high temperatures and has water vapor in the reactor feed, TRM ...
