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 ...
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 ...
Desenvolvimento e avaliação de filtros de poliacrilonitrila incorporados com nanopartículas e surfactantes para aplicação biocida na filtração de ar
(Universidade Federal de São Carlos, 2022-07-25)
Suspended particulate matter in the air represents a significant health risk, potentially leading to severe respiratory diseases. Bioaerosols, including viruses, bacteria, and fungi, are also part of this particulate matter ...
Síntese de catalisadores básicos na presença de surfactantes hexadeciltrimetilamônio
(Universidade Federal de São Carlos, 2023-06-12)
The synthesis of two basic catalysts — CTA-MCM-41 and ZIF-8 — were studied in the presence of the surfactant hexadecyltrimethylammonium bromide (CTAB), which forms micelles in aqueous dispersions. The catalysts were ...
