Síntese enzimática de ampicilina com diferentes substratos em reator integrado
(Universidade Federal de São Carlos, 2008-12-12)
Penicillin G acylase (PGA), EC 3.5.1.1.11, is an enzyme employed in the hydrolysis reactions of penicillin G to produce 6-amino penicillanic acid (6-APA), but it can also used in the synthesis of semi-synthetic antibiotics. ...
Estudo do comportamento da deposição das partículas de diferentes meios filtrantes
(Universidade Federal de São Carlos, 2008-03-17)
Many studies related to bag filters have focused on minimizing the amount of energy used in the process. Seeking longer filtration cycles, lower frequency of cleaning cycles and a longer filter life, such studies search ...
Isomerização do N-hexano sobre catalisadores Pt-Ni suportados na zeólita H-BEA nanocristalina
(Universidade Federal de São Carlos, 2008-11-11)
This work had as a goal to investigate the main factors that explain the highest activity of zeolite Beta in relation to the other zeolitic structures, using the n-hexane isomerization as a criterion. With this goal, in ...
Estudo do efeito da adição de Au, Pd e Pt em catalisadores Cu/CeO2 aplicados à reação de deslocamento gás-água a baixa temperatura
(Universidade Federal de São Carlos, 2008-07-02)
Cu/CeO2 catalysts doped with Au, Pd or Pt (WGSR) were prepared and applied in water gas shift reaction. The CeO2 support was prepared by four different way: urea co-precipitation-gelation (CeO2-UGC), hydrothermal method ...
Perovskitas contendo lantânio, ferro e cobalto - melhoramento de propriedades texturais via síntese por nanomoldagem e avaliação como catalisadores na redução de NO com CO
(Universidade Federal de São Carlos, 2008-10-20)
Mixed oxides with perovskite structure have high potential as catalysts in gas depollution processes and particularly in the abatement of nitrogen oxides (NOx). Such solids could be considered as a promising alternative ...
Fração de filme líquido nas paredes de um lavador Venturi
(Universidade Federal de São Carlos, 2008-07-10)
The study of the liquid film in the walls of a Venturi scrubber was chosen as the target of this work for representing one of the important phenomena that influence the collection efficiency of the equipment. Such efficiency ...
Monitoramento de reator enzimático para produção de ampicilina
(Universidade Federal de São Carlos, 2008-04-11)
This work is part of a research project in DEQ-UFSCar (Department
of Chemical Engineering at Federal University of São Carlos, Brazil). The focus is
to develop a competitive industrial enzymatic process to obtain semi-synthetic ...
Influência da taxa de carregamento orgânico na degradação anaeróbia da vinhaça em reator de leito fluidizado
(Universidade Federal de São Carlos, 2008-04-24)
In this work, the mesophilic anaerobic degradation (35 ºC) of the sugar cane vinasse
was studied in an anaerobic fluidized bed reactor (RALF) for 255 days. The reactor,
built in acrylic and with a total volume of 4,192 ...
Influência das condições de alimentação de glicerol e ornitina na produção de ácido clavulânico por Streptomyces clavuligerus
(Universidade Federal de São Carlos, 2008-03-26)
The clavulanic acid (CA) is a powerful inhibitor of β-lactamases, enzymes that clives the β-
lactam ring of penicillins and cephalosporins, inactivating these compounds. CA is
traditionally produced by Streptomyces ...
Monitoramento e controle de emissão de material particulado em uma fonte estacionária
(Universidade Federal de São Carlos, 2008-11-19)
The goal of this study was the monitoring of emissions by sources in Lower Furnace Production of Iron-alloy and Steam Generators of Industry Production of Alcohol. This tracking emission of pollutants was conducted after ...
