Imobilização de lipases pela técnica CLEA para síntese de biodiesel em reator de fluxo em vórtice
(Universidade Federal de São Carlos, 2017-10-30)
Due to the heterogeneity of the vegetable oils used in the synthesis of biodiesel, they can be transformed more quickly using a mixture consisting of lipases with different activities and specificities instead of single ...
Integração energética de biorrefinarias de cana-de-açúcar com operação multiperiódica
(Universidade Federal de São Carlos, 2018-01-16)
Brazil has a great importance as biofuels producer, especially of ethanol from sugarcane. The bagasse, a byproduct of sugarcane biorefineries, can be used to generate electricity and produce second generation
ethanol. ...
Secagem de cevada: análise da anatomia e do meio de transporte
(Universidade Federal de São Carlos, 2018-03-23)
Despite the recent motivations for application in the food industry, the characterization of polished barley grains is still scarce in the literature. In this way, the objective of this work was the experimental analysis ...
Estudo integrado das etapas de pré-tratamento e hidrólise enzimática da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2017-10-20)
The use of lignocellulosic biomass for ethanol production, such as, the sugarcane straw, suggests that additional steps should be included aiming the sugars release, that will be converted to ethanol via fermentative route. ...
Aplicação do método de lattice Boltzmann na simulação de meios filtrantes : implementação de códigos para geração do domínio de cálculo e condição de contorno de escorregamento
(Universidade Federal de São Carlos, 2018-03-19)
Many studies have been carried out to find the best operating point for filter media, and the mathematical modeling and simulation are becoming a important tool. In this work, a code was built to generate geometric models ...
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. ...
Modelagem, simulação e análise técnico-econômica-ambiental do processo de extração de óleo de soja por hexano e etanol e da produção de biodiesel
(Universidade Federal de São Carlos, 2019-07-04)
Brazil is the second largest producer of soybean, with the projection of becoming the largest producer in 2019/2020. All Brazilian soybean oil is produced by the extraction process with hexane, an oil derivative. One way ...
Análise do desempenho de meios filtrantes na filtração de nanopartículas durante o aumento de sua queda de pressão
(Universidade Federal de São Carlos, 2019-02-27)
The performance of filter media in filtration is the main factor in choosing a material that meets the requirements for a filtration process. It takes into consideration the collection efficiency, permeability, pressure ...
