Equipment Grant : Acquisition of an Excimer Gas Laser to Conduct Laser Photolysis/Laser-Induced Fluorescence Elemen- tary Kinetic Studies of Chlorohydrocarbon/Hydroxyl Reactions

将购买一台Lambda Physik LPX 105i CC准分子气体激光器，以提高准确测量氯代烃氧化和热解高温反应动力学的能力。该激光器最初将并入现有的激光光解/激光诱导荧光基本动力学测量装置。除了提供清洁的羟基自由基源外，这种泵浦激光还将用于在广泛的范围内改变光解能量密度，从而能够更彻底地评估二次反应。高温率数据和力学信息的获得将大大加强目前用于氯代烃燃烧过程的化学动力学模拟的数据库。为了了解、预测和控制废物热处理和其他工业过程中有毒排放物的形成，需要这些信息。

A Lambda Physik LPX 105i CC excimer gas laser is to be purchased to improve the ability to accurately measure the high temperature reaction kinetics of chlorinated hydrocarbon oxidation and pyrolysis. The laser will be initially incorporated into an existing laser photolysis/laser-induced fluorescence elementary kinetics measurement apparatus. In addition to providing a clean source of hydroxyl radicals, this pump laser will be used to vary photolysis energy densities over wide ranges, allowing a more thorough evaluation of secondary reactions. The acquisition of high temperature rate data and mechanistic information will strongly enhance the currently sparse data base for chemical kinetic modelling of combustion processes involving chlorinated hydrocarbons. This information is required in order to understand, predict, and control the formation of toxic emissions from the thermal treatment of wastes and other industrial processes.
