The Effects of Fuel Additives on Soot Formation

Abstract

The effect of an iron additive on soot formation during the pyrolysis and oxidation of benzene was studied in a conventional, 7.6-cm i.d. shock tube. Iron pentacarbonyl, Fe(CO)(5), as a surrogate for ferrocene, was used as the additive. As a control, carbon monoxide (CO) was also considered an additive. Measurements were carried out at two pressure levels (2-3 atm. and 5-7 atm.) over a temperature range from 1600-2400 K. No direct influence of iron could be demonstrated, although a weak effect would have been obscured by a surprisingly strong enhancement of sooting by CO during low-pressure pyrolysis and high- pressure oxidation. An indirect effect of iron was to reduce or eliminate the enhancement of soot yield by CO. Subject Terms: Soot Formation, Benzene, Fuel, Pyrolysis, Oxidation, Shock Tube, Optical Probe, Additives, Iron.
