Nanometric soot particles generated by incomplete oxidation of fuels have a negative impact on the climate change and human health. Although the soot production improves the radiative heat transfer in combustion systems, ...

Nanometric soot particles generated by incomplete oxidation of fuels have a negative impact on the climate change and human health. Although the soot production improves the radiative heat transfer in combustion systems, ...

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 ...

This work describes the development of stacked wire-mesh structures and their washcoating method to prepare a structured system for the catalytic combustion of soot. For this purpose, a metallic structured substrate was ...

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 ...

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 ...

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 ...

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 ...
