Diesel emission control: Catalytic filters for particulate removal

Diesel Particulate Filters [subscription]

● Diesel Filter Regeneration Abstract: Diesel particulate filters capture particle emissions through a combination of surface-type and deep-bed filtration mechanisms, such as diffusional deposition, inertial d positi , or flow-line interception. Collected particulates are removed from the filter, continuously or periodically, through thermal regeneration. Diesel filters are very effective in co...

Catalytic control of diesel engine particulate emission: Studies on model reactions over a EuroPt-1 (Pt/SiO,) catalyst

The catalytic ox&&Ion of mtnc oxide to mtrogen &oxide m the presence of sulphur dioxide over a standard Pt/S102 catalyst (EuroPt-1) was stuched The gas-phase reactions between mtnc oxide, sulphur choxlde and oxygen were found to be ms~gmficant under the expenmental conditions concerned The Pt/S102 catalyst was observed to be very actwe m catalyzing the reactions both of NO+ 0, to NO, and of SO2...

Particulate Removal Efficiency in Arterial Screen Filters

___ ____________ _ Six types of commercially available arterial screen filters ranging from 20 to 40 microns pore size were evaluated for their efficiency in removing particulate matter. Five filters of each of these six commercial types were tested, for a total of thirty filters. Three sizes of polystryene microspheres ranging from 25 to 53 microns in diameter were used to simulate particulate...

CFD Simulation of Soot Filtration in Diesel Particulate Filters

Soot emissions from automotive applications can be reduced through on-board diesel particulate filters (DPFs): the filter gets progressively loaded by filtering the soot laden flue gases, thus causing an increasing pressure drop, until an oxidative regeneration is induced by temperature rise. Due to the complexity of the involved phenomena, a fully predictive and detailed mathematical model rep...
