The chlorinating species in turbulent flame combustion of methane with hydrogen chloride present

Abstract

Combustion of methane with air in the presence of hydrogen chloride was studied in a turbulent jet-stirred burner. The reaction was monitored by in situ mass spectometry and the ratio of Cl2 2HCl intensities was measured as a function of equivalence ratio (Φ). For values of Φ = 1.25 - 0.5 (fuel rich to fuel lean flames) the ratio of Cl2 2HCl intensities was close to zero. For values of Φ < 0.5 the ratio of Cl2 2HCl intensities increased significantly. The interpretation is that hydrocarbon radicals, e.g. CH, strip Cl from HCl to produce chloromethyl radicals which are known to react to form simple chlorocarbons, chlorinated aromatics, chlorinated PAH and Dioxins. For Φ < 1.0 no chlorination was... (More)
