Hidrogenación selectiva de ácidos y ésteres para obtener alcoholes grasos insaturados con catalizadores de metal noble soportado
(2022-07-28)
La tesis se centra en el estudio de catalizadores Rh-Sn-B/γ-Al2O3, y Rh-Sn-B/TiO2, utilizados en la reacción de hidrogenación selectiva de ácido oleico y oleato de metilo para la obtención de alcohol oleico. Los catalizadores ...
Dissolved Air Flotation of arsenic adsorbent particles
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-01-01)
The removal of arsenic from synthetic effluent was studied using the adsorbent particle flotation technique (APF) and dissolved air flotation (DAF). A sample of an iron mineral was used as adsorbent particles of arsenic, ...
Effect of salinity and overgrinding on the flotation of malachite
(Universidad Michoacana de San Nicolás de Hidalgo, 2019-02)
In the present work, the effects of salinity and overgrinding on the flotation of malachite were investigated. First, malachite flotation behaviors were studied with different collectors, namely, salicylaldoxime, ...
