Chemical Transformations in Photochemical Smog and Their Applications to Air Pollution Control Strategies

摘要

The need for computer modeling of photochemical smog to assess the complex interactions between energy policies and air quality programs is addressed. Described is the development of consistent and chemically acceptable kinetic models for n-butane/NOx/air and propylene/NOx/air photo-oxidation reactions. Experimental results indicate that although satisfactory agreement was obtained between calculated and experimental concentration-time profiles for most of the propane and n-butane runs, too many uncertainties remain in the OH-olefin and O3-olefin reactions to consider validation complete. Also presented are results of model tests based on specific chemical reactions; chamber studies of hydrocarbon reactivities; the formation and role of particulates in photochemical air pollution; the evaluation of analytical methods and calibration procedures for ozone analysis; and analysis of trace organic contaminants by combined gas chromatography-mass spectrometry.
