Effects of three oxygenate additives (methanol, ethanol, and MTBE) on the formation of polycyclic aromatic hydrocarbons (PAHs) and soot in laminar, premixed, atmospheric pressure, fuel-rich flames of n -heptane were studied at an equivalence ratio of 2.10. A heated quartz microprobe coupled to online gas chromatography/mass spectrometry was used to establish the identities and absolute concentrations of major, minor, and trace species by the direct analysis of samples withdrawn from the flames… 

Reduction of PAH and soot precursors in benzene flames by addition of ethanol.

A one-dimensional premixed flame model (PREMIX) and schemes resulting from the merging of validated kinetic schemes for the oxidation of the components of the present mixtures (benzene and ethanol)

Chemical Effects of CO2 and H2O Addition on Aromatic Species in Ethanol/Air Diffusion Flame

ABSTRACT Exhaust gas recirculation (EGR) is an effective technique used widely to meet current emission regulations. In this work, the mechanism of H2O and CO2 addition (a main component of exhaust

The Potential of Oxygenates to Increase the Risk of Exposure to Polycyclic Aromatic Hydrocarbons through Groundwater Contamination

The Clean Air Act (42 U.S. Code § 7401) is one of the United States of America’s most influential environmental laws. Under the Clean Air Act Amendments of 1990, oxygen-containing organic compounds

Effects of alcohol addition to traditional fuels on soot formation: A review

Soot is one of the main pollutants produced by incomplete combustion of hydrocarbon fuels, which poses a serious threat to human health and the urban environment. Alcohols have been generally

Variations of the Soot Precursors Chemical Composition Induced by Ethanol Addition to Fuel

In this study, conventional analytical methods such as infrared spectroscopy, 1H NMR, elemental analysis, and vapor pressure osmometry were combined to calculate the average structural parameters of


ABSTRACT Results are presented from a combined experimental and modeling study undertaken to understand the pathways by which the addition of dimethyl ether (DME) to fuel-rich ethylene flames causes



Fluorescence spectra and polycyclic aromatic species in a N-heptane diffusion flame

Experimental Study of 1 Atmosphere, Rich, Premixed n-heptane and iso-octane Flames

Temperature and species mole fraction profiles have been measured in laminar premixed n-heptane/O2/N2 and iso-octane/O2/N2 flames. Both flames have been stabilized on a flat-flame burner, at

The Oxidation of N-Heptane in the Presence of Oxygenated Octane Improvers: MTBE and ETBE

Abstract The oxidation of n-heptane and mixtures n-heptane-MTBE (50:50) and n-heptane-ETBE (50:50) has been studied experimentally in a high-pressure jet-stirred reactor in a wide range of conditions
