Preparação e caracterização de derivados de enzimas industriais em quitosana
(Universidade Federal de São Carlos, 2008-04-25)
In this work, several strategies were tested to improve the covalent multipoint attachment of chymotrypsin, carboxypeptidase A and cellulase on chitosan. Hybrid gels with different internal structures were obtained using ...
Eletrodissolução de alumínio em polpa celulósica proveniente da reciclagem de embalagens cartonadas multicamadas
(Universidade Federal de São Carlos, 2009-03-09)
In this work we studied the aluminum electro-dissolution in cellulose pulp from milk and beverage cartons recycling. The objective for this research is to reduce the aluminum particles sizes to values below 300 μm. ...
Liofilização de frutas tropicais
(Universidade Federal de São Carlos, 2008-08-21)
The national and international markets of processed fruits have continually grown due to the improved quality of the marketed product, the convenience of ready-to-serve products and because the availability of seasonal ...
Influência do método de preparação de catalisadores bifuncionais, Pt-Ni/HUSY, na isomerização do n-hexano
(Universidade Federal de São Carlos, 2008-02-25)
Gasoline containing high amount of linear chain compounds have low
octane number. However, this number can be increased when linear alkanes are
subjected to isomerization, able to change linear chain compounds to ...
Isomerização do n-heptano sobre catalisadores bifuncionais Pt-Ni suportados em zeólitas BEA e FAU
(Universidade Federal de São Carlos, 2009-12-09)
The objective of this paper was to study the influence of metal loading content on the properties of bimetallic catalysts, formed by Pt and Ni, supported on zeolite HUSY and HBEA. Another objective of this study was to ...
Separação de ampicilina produzida enzimaticamente por reação entre éster metílico de fenilglicina e ácido 6-aminopenicilânico.
(Universidade Federal de São Carlos, 2003-11-07)
The separation/concentration process of the products obtained from the enzymatic synthesis of ampicillin (AMP) catalyzed by immobilized penicillin G acylase was the focus of this Thesis. Hydrophobic resin adsorption and ...
Busca heurística e inferência de parâmetros cinéticos de reações de hidrotratamento de óleo diesel a partir de dados experimentais escassos
(Universidade Federal de São Carlos, 2011-06-30)
Currently, the amount of contaminants (such as sulfur, nitrogen and aromatics) in diesel oil is strictly controlled, due to their impact on pollutant emissions. The most important process used to meet fuel specifications ...
Redução de cromo hexavalente utilizando-se filmes de polímeros condutores como materiais eletródicos.
(Universidade Federal de São Carlos, 2003-06-16)
In this work we studied a three-dimensional electrode (reticulated vitreous carbon, CVR), modified with conducting polymer films, for the electrochemical reduction of Cr(VI). First of all, the conducting polymers polyaniline ...
Nanopartículas de Pt suportadas em Al2O3 e CeO2-Al2O3: síntese e caracterização de catalisadores aplicados à reação de deslocamento gás-água
(Universidade Federal de São Carlos, 2011-04-28)
Colloidal Pt nanoparticles were synthesized according to an adapted procedure from Song and co-workers [1], which it was based on the reduction of dihydrogen hexachloroplatinate by ethylene glycol in a basic solution, but ...
Operação periódica de um leito gotejante de carvão ativado para redução da emissão do poluente atmosférico SO2 com geração de ácido sulfúrico.
(Universidade Federal de São Carlos, 2003-06-23)
A laboratory-scale investigation of SO2 scrubbing was carried out in a 77.92mm (diameter) × 80.00mm trickle bed with 2.00-2.36mm activated carbon particles using continuous and periodically interrupted liquid flows. The ...
