Catalisadores Cu-, Co- ou Fe-ZSM-5 caracterização e avaliação na redução de NO a N2 com hidrocarbonetos na presença ou ausência de vapor de água.
(Universidade Federal de São Carlos, 2005-03-04)
The minimization of the emissions of nitrogen oxides (NOx) in the atmosphere has been one of the great goals in the area of environmental
protection. Among the possible processes to treat the NOx, the selective catalytic ...
Estudo da transferência de calor e massa no processo de secagem em leito vibro-fluidizado.
(Universidade Federal de São Carlos, 2003-09-05)
Drying processes in fluidized and vibro-fluidized beds are nowadays being widely
investigated in the literature, because such beds offer many advantages over other types of
dryers. The purpose of this work is to contribute ...
Secagem de sementes de Arachis hipogae L. com capa protetora
(Universidade Federal de São Carlos, 2009-02-20)
Arachis hipogae L. peanut is an orthodox seed that must go through a drying process to become free from aflatoxin. The fruit is formed by a system made up by a nucleus and a resistant involucre that constitutes a heterogeneous ...
Efeito do teor de CeO2 em catalisadores de Pt/CeO2-Al2O3 para as reações de oxidação parcial e reforma do metano.
(Universidade Federal de São Carlos, 2005-03-10)
The effect of CeO2 loading in Pt/CeO2-Al2O3 catalysts was investigated. Pt
catalysts supported on mixed CeO2-Al2O3 carriers with different CeO2 loading 1,
3, 6, 12, 20 wt.% were prepared by incipient wetness impregnation ...
Comportamento da filtração de gases em meios filtrantes de celulose.
(Universidade Federal de São Carlos, 2006-09-15)
The present work aims to evaluate, through filtration process and cake detachment, the
behavior of two cellulose fiber filtering media with different air permeability values. The
powder material used was phosphatic ...
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. ...
Desenvolvimento de um leito vibro-fluidizado e estudos dos coeficientes de transferência de calor de corpos submersos.
(Universidade Federal de São Carlos, 2003-07-29)
In this work equipment developments and techniques for aerodynamics and heat transfer studies in a vibro-fluidized bed are presented. The equipment projected and built consists of an acrylic bed with a circular section of ...
Estudo da purificação do àcido clavulânico utilizando processo contínuo de adsorsão.
(Universidade Federal de São Carlos, 2003-10-02)
Clavulanic acid (CA), a beta-lactam antibiotic, has been known for its commercial and therapeutic importance. This antibiotic is produced by an actinomicete, Streptomyces clavuligerus, and has a combined use with penicillins, ...
