Fuel Additives for Particulate Matter/Dust Reduction

Abstract

This review covers the recent reports related to the recent developments in the field of application of various types of fuel additives for reduction of particulate matter/dust in exhaust gases resulting from incomplete combustion of hydrocarbon fuels. Different aspects of these emissions like the concern about polycyclic aromatic hydrocarbons adsorbed on soot particles, the trade-off between PM and NOx emission, etc. are presented. The metallic, organometallic and non-metallic additives including oxygenates, nitrogenates and nitro-oxygenates have been described in reference to various types of fuels like heavy fuel oil, diesel, mixed fuels, biodiesels and gaseous fuels. Progress made in deciding the probable mode of action of these additives has also been incorporated.
