Shock tube and modeling study of isobutene pyrolysis and oxidation
چکیده انگلیسی
Pyrolysis and oxidation of isobutene were studied behind reflected shock waves in the temperature range 1000-1800 K at total pressures between 1.0 and 2.7 atm. The study was carried out using following method: (1) a single-pulse technique for product yields, (2) time-resolved IR-laser absorption at 3.39 μm for isobutene decay and formation rates of compounds which contain C-H bond, (3) time-resolved IR emission at 4.24 μm for CO2 formation rate, and (4) time-resolved UV absorption at 306.7 nm for OH radical formation rate. The pyrolysis and oxidation of isobutene were modeled using a reaction mechanism including the sub-mechanisms for methane, acetylene, ethylene, ethane, formaldehyde, allene, propyne, propene, and ketene oxidation. The reaction mechanism used in the present study could reproduce all experimental results.
