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 ...
Proteína de soja como aditivo na sacarificação enzimática da biomassa vegetal: desenvolvimento e análise tecno-econômica do processo
(Universidade Federal de São Carlos, 2019-02-28)
The implementation of the biochemical conversion process of lignocellulosic biomass into biofuels and other bioproducts still have some technological challenges to be overcome, such as low yield of the enzymatic hydrolysis ...
Catalisadores à base de Ni/(CeZr)O2/MgAl2O4 e Ni/(X2O3+ZrO2)/MgAl2O4 (X=La, Sm e Y) aplicados à tri-reforma do metano visando produção de hidrogênio e gás de síntese
(Universidade Federal de São Carlos, 2019-03-26)
The Methane Tri-Reforming (MTR) is a combination of Methane Dry Reforming (MDR) and Methane Steam Reforming (MSR) coupled with the Partial Oxidation of Methane (POM). In the present work, nickel catalysts supported on ...
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 ...
Obtenção e caracterização de levedura recombinante com elevada tolerância a etanol por engenharia evolutiva
(Universidade Federal de São Carlos, 2019-02-22)
The utilization of the hemicellulosic fraction of the biomass is important for the economic viability of the industrial production process for second generation bioethanol. Wild strains of Saccharomyces cerevisiae do not ...
Catalisadores de Ni suportados em óxidos sintetizados com líquido iônico: atividade catalítica na tri-reforma do metano
(Universidade Federal de São Carlos, 2019-04-11)
Tri-reforming reaction is a new method to use and convert CO2 from industrial plants effluents. The tri-reforming involved reactions are two endothermic reactions, the steam and dry reforming and the partial methane oxidation ...
Avaliação de suportes hidrofóbicos aplicados à purificação de enzimas
(Universidade Federal de São Carlos, 2019-02-28)
Enzymes are biological catalysts that present diverse applications, representing interesting perspectives for use in several branches of the industry: agribusiness, biofuels, and pharmacist. However, the recovery of broth ...
Estudo da produção de etanol a partir de xilose e xilooligômeros usando xilanases, xilose isomerase e levedura co-imobilizadas
(Universidade Federal de São Carlos, 2019-04-24)
The production of ethanol from xylose with the yeast Saccharomyces cerevisiae was initiated in the group with the SIF process (simultaneous isomerization and fermentation). This process allows total conversion of xylose, ...
Interpoladores multilineares como metamodelos: integração à simulação de biorrefinarias no ambiente EMSO
(Universidade Federal de São Carlos, 2018-03-26)
The use of equation oriented simulators presents several advantages, mainly the separation between the mathematical model and the algorithm responsible for its resolution. This allows an easy implementation of new models ...
Análise das propriedades de fluxo de diferentes tipos de açúcar
(Universidade Federal de São Carlos, 2017-02-22)
Various processes in food, pharmaceutical and chemical industries have to handle with solid particles at some point during their processes. From the manufacturing process to storage of these materials, interparticle forces ...
