Ozone Productivity of Atmospheric Organics, Coordinating Research Council ProjectA-10. Final Report

摘要

This project addresses elucidating the fundamental chemical basis of incrementalreactivities. The value of the incremental reactivity of a particular compound, given its atmospheric oxidation mechanism, depends on the VOC/NOx mixture in which the compound is imbedded. The dependence of incremental reactivity on the base VOC/NOx mixture has been an issue of concern since the introduction of the incremental reactivity as a regulatory concept. This project answers the basic question: how and why does the incremental reactivity of a compound change as the base VOC/NOx mixture is changed, both with respect to the individual VOC combustion and with respect to the overall VOC/NOx ratio. This paper is composed of several papers which describe the methodology used to examine incremental reactivities, indicate to what factors the incremental changes in ozone can be attributed, and explain the incremental reactivities of fuel oxygenates based on their reaction chemistry.
