A high pressure laminar flow reactor facility (HPLFR) was designed and constructed to serve as a platform for the experimental study of the gas phase chemistry of small molecule species. This facility accommodates pressures from slightly above atmospheric to ~30 atm, temperatures from ambient to ~1000 K, and plug flow residence times on the order of 100 milliseconds to 10 seconds. Quasi-steady state NOx plateau (QSSP) experiments were conducted in the newly-constructed HPLFR to determine rate coefficients for the reaction H+O2(+M)↔HO2(+M) (H.9.M) relative to the reasonably well-known rate coefficient for H+NO2↔OH+NO. Initial experiments for M = Ar and N2, for …
