Heterogeneous Chemistry in Solid Rocket Motor Plumes.
Abstract
Reaction rates of ozone decomposition and adsorption/desorption rates of HCl on aluminum oxide (alumina) particles were measured by a new technique involving real-time ultraviolet absorption spectroscopy in a static reactor. Reaction probabilities eta are reported for ozone on alpha-alumina, gamma-alumina, and chromatographic alumina (hydoxylated alumina), respectively, over the temperature range -60 to 200 deg C. These measurements expand on previous measurements from this group using a flow tube reactor. The adsortion/desorption kinetics is a new effort that addresses the key issue of whether heterogeneous chemistry, such as the reaction HCl + ClONO2 --> Cl2 + HNO3, on alumina particles is a significant reaction mechanism for global stratospheric ozone depletion.
