Metodologia para guiar o desenvolvimento e implementação industrial de novas tecnologias unindo engenharia econômica e Engenharia de (bio)processos e sistemas : aplicação à produção de etanol de segunda geração
(Universidade Federal de São Carlos, 2016-03-18)
Lignocellulosic ethanol, also called second generation ethanol, is a promising alternative for decreasing fossil fuel dependency globally. Nevertheless, its production process still needs further improvements in order to ...
Avaliação da fermentação alcoólica extrativa em diferentes temperaturas com remoção de etanol por arraste com CO2
(Universidade Federal de São Carlos, 2023-02-23)
By reducing the fermentation temperature, the inhibitory effect of ethanol is also reduced, resulting in wines with higher ethanol contents, but with a significant decrease in ethanol productivity, due to the negative ...
Encapsulamento de Trichoderma harzianum em matrizes à base de nanocelulose e carboximetilcelulose para aplicação na agricultura
(Universidade Federal de São Carlos, 2023-06-21)
Microbial inoculants are a sustainable alternative to increase agricultural productivity and reduce environmental and health problems caused by the exacerbated use of agrochemicals. These bio-based products are formulations ...
Modelos preditivos para equilíbrio de fases de misturas hidroalcoólicas multicomponentes presentes na concentração e desidratação de etanol de 1ª e 2ª geração
(Universidade Federal de São Carlos, 2017-06-30)
The production increase of the ethanol from sugarcane, ensuring energy and environmental viability, goes through the development of the step with highest energy consumption: the separation process in the distillation ...
Cristalização e separação de KCI a partir de carnalita : síntese de processo, simulação e viabilidade econômica
(Universidade Federal de São Carlos, 2018-02-21)
Due to the increasing demand for potassium in Brazil, it is feasible to exploit carnallite in order to supply part of the national need for this alkali metal, whose reserves of raw material - in this case sylvite - are ...
Estudo da secagem de grãos em leito fixo, com e sem escoamento reverso do ar de secagem
(Universidade Federal de São Carlos, 2019-03-25)
Attempting to contribute to the development of the drying process in fixed bed, this work has the objective of the experimental study on the drying of barley grains in fixed bed, without and with drying airflow reversal. ...
Preparação e caracterização de sílicas híbridas com surfactantes catiônicos
(Universidade Federal de São Carlos, 2018-02-16)
The silica with structure MCM-41 has a hexagonal mesoporous arrangement with one dimensional pore system. This silica as synthesized contains cations (usually the CTA+) in your pores and catalytic sites with basic character ...
Fermentação alcoólica extrativa com remoção de etanol por arraste com CO2 e recuperação por absorção
(Universidade Federal de São Carlos, 2019-02-28)
Ethanol removal by CO2 stripping during alcoholic fermentation is one way of overcoming the problem of inhibition by the ethanol. However, the lack of efficient methods to recover the removed ethanol still makes the use ...
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 ...
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 ...
