Mitigação dos inibidores gerados no pré-tratamento da biomassa vegetal: impacto técnico-econômico-ambiental de diferentes rotas de processo na biorrefinaria
(Universidade Federal de São Carlos, 2021-04-27)
The presence of inhibitors is still an economic bottleneck that needs to be resolved in order to make 1G2G ethanol biorefineries feasible, requiring the development of technologies capable of improving their competitiveness ...
Produção de etanol 2g em reator de leito fixo e por bioprocessamento consolidado utilizando leveduras de alta performance
(Universidade Federal de São Carlos, 2021-05-06)
In order to enable the industrial production of second generation (2G) ethanol, the
development of processes with high productivity using hydrolysates of lignocellulosic
material containing high concentration of ...
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 ...
Estudo de catalisadores bimetálicos de platina ou paládio e cobre suportados em céria para a reação de PROX-CO
(Universidade Federal de São Carlos, 2016-10-13)
In the present work, catalysts were prepared xCuO / CeO2 (x = 1.0 and 3.0% by mass)
doped with Pt or Pd for application in the preferred oxidation reaction of carbon
monoxide, also known as PROX-CO reaction. The catalysts, ...
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 ...
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 ...
Catalisadores de Ni/Al2O3 promovidos com Au e Ag aplicados à reforma a vapor do metano
(Universidade Federal de São Carlos, 2005-04-08)
15%Ni/Al2O3 catalysts was obtained by impregnation with Ni(NO3)2
aqueous solution and promoted with Au and Ag. The Au was successively
impregnated with aqueous solution of [Au(NH3)4](NO3)3. The Ag was coimpregnated
with ...
Produção de esferoides de células tumorais de câncer de bexiga num biorreator de vórtice de Taylor
(Universidade Federal de São Carlos, 2018-03-08)
Two-dimensional (2D) cell culture has been the common platform for evaluating anticancer drugs. However, three-dimensional (3D) cell cultures, such as multicellular tumor spheroids (MCTS), best resemble tumor in vivo ...
