✦ Synopsis

An experimental and modeling study of the oxidation of H2S is reported. The experiments entailed induction time measurements in reflected shock waves, in 4 to 22% H2S in air, some of which contained from 1.6 to 13% HzO, with PI = I atm and 950 < T 5 < 1200°K. Regression analyses gave the induction time formulas r = 10 74 exp ( 13000/T)[HzS]03z (with r in seconds, T in degrees Kelvin, and [H2S] in tool cm-3) for dry test gas and r = 10 s2 exp ( 13400/T)lH2S]O t8 for moist test gas. Computer modeling using a 17-species, 57-reaction mechanism led to reasonably satisfactory agreement between model calculations and experiments, including earlier studies on H2S combustion.
