| 摘要 |
The present invention relates to a method of purifying a flow of a gas, in particular an exhaust gas from a Diesel engine, which is contaminated with a particulate material (e.g. nanoparticles) using an apparatus comprising (i) a conduit for passage of the gas flow, (ii) means for applying electromagnetic radiation, e.g. microwaves, and (iii) means for supplying a dipolar liquid, e.g. water, said method comprising the steps of allowing the contaminated gas to flow through the conduit; and applying the electromagnetic radiation to said gas and said liquid. The invention also relates to an apparatus, e.g. a diesel engine exhaust system for purifying a continuous exhaust gas flow contaminated with particulate material(s), e.g. nanoparticles, in order to reduce the content of nanoparticles.
