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 ...
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 ...
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. ...
Sacarificação e isomerização simultâneas de dextrina na produção de xarope de frutose por ação sinérgica de CLEAs magnéticos de amiloglicosidase e Sweetzyme®
(Universidade Federal de São Carlos, 2019-07-25)
High fructose syrup is a sweetener widely used as a substitute for sucrose by the food and beverage industry. It has many advantages such as relative sweetness superior to sucrose, high solubility, crystallization resistance ...
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, ...
Síntese da zeólita Beta usando planejamento experimental e emprego na isomerização do n-hexano
(Universidade Federal de São Carlos, 2012-09-14)
This work aimed to apply the Design Of Experiment (DOE) methodology as an auxiliary tool to evaluate the conditions of synthesis of the aluminum-rich zeolite Beta. Bimetallic catalysts with 50% platinum and 50% nickel ...
Produção de sulfato de potássio a partir de cloreto de potássio e sulfato de amônio : estudos de equilíbrio sólido-líquido e desenvolvimento de processo
(Universidade Federal de São Carlos, 2016-02-29)
Potassium is one of the basic nutrients for plants and their concentration in the soil is
insufficient to produce high quality crops, so it should be an essential component in the
composition of fertilizers. Fertilizers ...
Estudo do pré-tratamento hidrotérmico e hidrólise enzimática da palha de cana-de-açúcar
(Universidade Federal de São Carlos, 2016-04-08)
The complex cell wall structure of lignocellulosic biomass makes pretreatment one of the most
relevant 2G ethanol production process steps due to the difficulty of hydrolyzing lignocellulose
to fermentable sugars and the ...
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 ...
