Sooting behaviors of n-butanol and n-dodecane blends

A review of the combustion and emissions properties of advanced transportation biofuels and their impact on existing and future engines

“…Droplet combustion experiments of n-butanol showed very low soot levels due to less acetylene production during the combustion process [271]. Blends of n-butanol with n-dodecane show a reduced sooting propensity for butanol, but also a lower rate of soot oxidation after it is formed that can slow soot burnout before exhaust [272], which could lead to higher net PM emissions.…”

Impacts of oxygenated compounds concentration on sooting propensities and soot oxidative reactivity: Application to Diesel and Biodiesel surrogates

“…They also found that the surface oxygen content is proportional to the soot oxidative reactivity and may be the main factor for oxidation reactivity of oxygenated soot. On the other hand, Ghiassi et al [24] studied the impact of n-butanol addition at different mole fractions (10% / 30% / 60%) on a Diesel surrogate, i.e. n-dodecane.…”

Soot formation in non-premixed counterflow flames of butane and butanol isomers

“…The investigation of their fundamental properties assists in the design of advanced engines to control the combustion processes. This is evident as there have been numerous fundamental combustion studies of butanols conducted on laminar premixed and non-premixed flames [e.g., [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], flow reactors [e.g., [26][27][28][29][30][31], ignition delays in shock tubes [e.g., [32][33][34][35][36][37][38][39][40][41] and rapid compression machines [e.g., [42][43][44][45], fuel pyrolysis [e.g., [46][47][48][49][50], and jet stirred reactors [e.g., 7,13,…”
