Diesel/biodiesel soot oxidation with ceo2 and ceo2-zro2-modified cordierites: a facile way of accounting for their catalytic ability in fuel combustion processes
(Sociedade Brasileira de Química, 2011)
CeO2 and mixed CeO2-ZrO2 nanopowders were synthesized and efficiently deposited onto cordierite substrates, with the evaluation of their morphologic and structural properties through XRD, SEM, and FTIR. The modified ...
Catalytic Combustion of Diesel Soot: Experimental Design for Laboratory Testing
(Elsevier Science Sa, 2009-10)
In order to abate diesel soot particles many catalysts have been studied at several industrial and academic laboratories. However, the comparison of kinetic data obtained with such catalysts is not straightforward, due to ...
Catalytic ceramic papers for diesel soot oxidation: A spray method for enhanced performance
(Elsevier Science, 2015-09)
A spraymethod is proposed to improve the catalytic properties of ceramic papers to be used as catalytic lters for removing diesel soot particles. Small particles of Ce and Co oxides, acting as active centers for the ...
Catalyst formulation to avoid reaction runaway during diesel soot combustion
(Elsevier Science, 2009-10)
Soot combustion is a highly exothermic reaction. The aim of this work is to demonstrate that catalyst overheating by reaction runaway can be moderated by the proper selection of a catalyst support, La2O3 being a good choice ...
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 ...
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 ...
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 ...
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 ...
Catalytic ceramic paper for the combustion of diesel soot
(Elsevier Science, 2010-10)
This work analyzes the application of a ceramic paper to the diesel soot combustion reaction in air. The catalytic paper is made of ceramic fibers, cerium oxide and potassium nitrate. The synthesis of this material is easy ...
