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 ...
