Avaliação da transferência de quantidade de movimento, energia e das espécies químicas em um prato perfurado de destilação através da fluidodinâmica computacional
(Universidade Federal de São Carlos, 2016-03-24)
The development of the design of chemical processes has received increasing improvement, incorporating sophisticated mathematical models, which allowed better simulation of its real behavior. Distillation is one of the ...
Lipases imobilizadas em suportes híbridos como biocatalisadores para a produção de ésteres de açúcares
(Universidade Federal de São Carlos, 2016-05-25)
The use of lipases in large scale processes is limited due to their high cost. The reuse of the catalyst can contribute to make the enzymatic process more attractive. Hydrophobic supports are the mostly used for lipase ...
Catalisadores à base de ferro, vanádio e molibdênio suportados em titanatos lamelares e TiO2 comercial na aplicação da reação de NO com NH3
(Universidade Federal de São Carlos, 2011-10-27)
The minimization of emissions of nitrogen oxides (NOx) is a subject of great interest because they cause serious environmental problems affecting human health, flora and fauna. To break down the NOx catalytic reduction of ...
