Desenvolvimento de sistema em fluxo empregando ultrassom para remoção de enxofre de óleo diesel
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2011-02-18)
In this work, the development of a continuous flow process for sulfur removal
from diesel oil is proposed. The process is based on the application of ultrasonic
energy for increasing the oxidation reaction rate of sulfur ...
Revisão dos métodos alternativos à hidrodessulfurização do diesel: desafios e perspectivas
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia QuímicaUTFPR, 2018-06-15)
Combustion of petroleum products, such as diesel, releases NOx, SO2 gases and particulate matter, causing air pollution, acid rain and damaging human health. In view of this, environmental legislation is increasingly ...

Avaliação da dessulfurização de diesel utilizando adsorventes mesoporosos modificados pós-situ com íons metálicos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2015-12-21)
The emission of sulfur compounds from the burning of oil products, such as diesel and gasoline, is responsible for causing environmental damage to human health and increase industrial costs. In this work, adsorptive processes ...
Liquid-liquid extraction: A promising alternative for inhibitors removing of pentoses fermentation
(Elsevier B.V., 2019-04-15)
Dilute sulfuric acid pretreatment is effective at producing a xylose-rich hydrolysate from lignocellulosic biomasses, however inhibitory compounds, released during the processes, can affect the metabolism of fermenting ...

Dessulfurização oxidativa em diesel utilizando catalisadores à base de vanádio ou manganês
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em QuímicaFísico-Química; Química, 2012-07-20)
The oxidative desulfurization process (ODS) of a commercial diesel fuel was performed
under mild conditions in the presence of catalysts based on vanadium or manganese,
supported on alumina, clays (commercial, natural and ...
Estudio teórico de la reactividad de los productos de la isomerización del trimetildibenzotiofeno
(Universidad Michoacana de San Nicolás de Hidalgo, 2013-09)
Oil is a nonrenewable resource that sustains society as we know it. Its derivatives are present in almost all daily activities. One of the most important derivatives are fuels such as gasoline and diesel. Even in these ...
