Catalizadores de oxidos de colbalto, cobre y niquel soportados sobre zirconia para la combustión catalítica de propano y naftaleno
(Universidad Nacional de La Plata, 2015-12)
Debido al incremento de contaminación atmosférica en este trabajo se busca diseñar catalizadores activos para disminuir la concentración de contaminantes presentes en fuentes móviles de emisión. Particularmente se busca ...
Total oxidation of propane and naphthalene from emission sources with supported cobalt catalysts
(Springer, 2016-07-15)
Propane and naphthalene combustion reactions were studied in the presence of CoOx/SiO2 catalysts. The catalysts were prepared by impregnation with four different levels of concentration (1, 5, 10 and 15 wt%) and characterized ...
Diesel soot combustion: KNO3 and KOH catalysts supported on zirconia
(Springer, 2008-06)
KNO3/ZrO2 and KOH/ZrO2 catalysts were studied and found active in the catalytic soot combustion. Two equipments were used to carry out the combustion experiments: a thermogravimetric reactor with an O2/He feed and a fixed ...
Cobalt and KNO3 supported on alumina catalysts for diesel soot combustion
(Elsevier Science Sa, 2010-05-07)
The catalytic combustion of diesel soot was studied in the presence of fresh and aged catalysts: Co/Al2O3, KNO3/Al2O3 and Co/KNO3/Al2O3. The catalysts were prepared by impregnation using nitrate solutions. The catalysts ...
Catalytic combustion of soot with a O2/NO mixture. KNO3/ZrO2
(Elsevier Science, 2003-12)
Catalysts containing 0.25–20% KNO3 supported on ZrO2 have been studied for diesel soot combustion. The addition of KNO3 to ZrO2 support enhances its activity due to the increased contact between soot and catalyst and also ...
Catalysts of alkaline nitrates supported on oxides for the diesel soot combustion. Deactivation by hydro-treatment and CO2.
(Elsevier, 2013-01-20)
The deactivation of supported catalysts CsNO3 and LiNO3 for diesel soot combustion is studied in this work. The effect of hydro-treatment at high temperature and presence of CO2 in feed flow were investigated. Catalysts ...
Combustion of diesel soot in NO/O2 presence. Cesium nitrate and gold catalysts
(Elsevier Science, 2011-01-29)
The diesel soot combustion was studied using catalysts prepared by impregnation with cesium nitrate and/or gold on zirconium oxide (ZrO2), hydrated zirconium oxide and silica (SiO2). Catalysts were characterized by ...
Evaluation of silica as an adsorbent for carbendazim from aqueous solutions
(Engineering Research Publication, 2015-02)
Adsorption of carbendazim onto silica has been studied. The influence of contact time, pH, ionic strength and temperature has been determined. The adsorption isotherms can be described by the Langmuir model. Adsorption ...
