Abstract
We present the coupling of a jet-stirred reactor to detection by cw-CRDS in the near infrared and first results obtained during the oxidation of methane. The mixture is rapidly expanded from the jet-stirred reactor into a 80 cm-long cw-CRDS cell maintained at a the pressure around 1.33 kPa, thus freezing the reaction and decreasing pressure broadening of the absorption lines. Some stable species (CH, HO and CHO) have been quantified through their well structured spectra around 1506 nm, while HO and HO radicals could not be detected.
摘要
我们展示了将喷射搅拌反应器与近红外连续波腔衰荡光谱（cw-CRDS）检测相结合，并给出了甲烷氧化过程中获得的首批结果。混合物从喷射搅拌反应器迅速膨胀至一个长80厘米的cw-CRDS池，该池维持在约1.33千帕的压力下，从而使反应冻结并减小吸收线的压力展宽。一些稳定物种（CH、HO和CHO）已通过其在1506纳米附近结构良好的光谱进行了定量，而HO和HO自由基未被检测到。
