INVESTIGATION OF LOCALIZED RAPID SOOT OXIDATION USING METALASSISTE HIGH FREQUENCY ELECTROMAGNETIC HEATING

Soot is a black carbon, produced from the incomplete combustion of diesel fuel, seen
as a black smoke when it is emitted from diesel engines. Soot has dangerous impacts
on the environment and human health. Hence, there are many regulations to reduce
soot emissions. Current measures include the use of particulate matter filters to trap
the soot from the exhaust gas. However, the increasing trapped soot in the filter leads
to blockage of the filter, resulting in reducing of the engine efficiency and may lead to
the engine damage. Therefore, filter regeneration strategies are used to oxidize the
soot. One of the efficient strategies is high frequency electromagnetic or microwave
heating. The drawbacks of microwave heating for soot filter regeneration are nonuniform
regeneration, non-effective on soot of a small thickness, and excessive
heating in the presence of a thick soot layer, which damages the filter.
