High temperature thermal decomposition of methanol

OSTI ID:6844018
The thermal decomposition of methanol (CH/sub 3/OH) was studied in both conventional and single-pulse shock tubes over the temperature and pressure ranges 1300-2000 K and 1.5-12.5 atm, respectively. In both studies, highly diluted CH/sub 3/OH mixtures in Ar were shock heated behind reflected waves. In the conventional shock tube infrared emission at both 3.47 and 9.56 ..mu..m was monitored in order to measure concentration as a function of time. The CH/sub 3/OH concentration profiles were characterized by overall global expressions. Quenched samples from the single-pulse shock tube were analyzed by gas chromatography. The data obtained from the two sets of experiments were utilized to develop a 30 reaction mechanism which models the thermal decomposition of CH/sub 3/OH better than previously proposed mechanisms.
