Research Equipment Grant: Gas Chromatography/Spectrometer Instrumentation

将使用此设备补助金购买带有质量选择检测器的气相色谱仪/质谱仪（GC/MS）。这将补充和加强化学工程部门现有的分析能力，具体应用于研究氯化液体和固体燃料的燃烧，旨在了解二恶英和呋喃等中间产物的形成和破坏。具体目标是获取喷床和固定床反应器中PCDD/ pcdf的动力学数据，以便更好地了解公认的形成机制；阐明温度、停留时间、前驱体分压和粒度对速率和产率的影响；模拟这些过程；并确定需要更深入研究的步骤和参数。GC/MS将大大提高对许多样品进行定量分析的能力。这反过来又将提高更好地理解与可能的前体的关系的可能性，并根据这种知识，可以解决实际焚化炉中某些操作和设计参数对不完全燃烧产物的作用。

A gas chromatograph/mass spectrometer (GC/MS) with a mass selective detector is to be purchased with this equipment grant. This will compliment and enhance existing analytical capabilities within the chemical engineering department, with specific applications to research on the combustion of chlorinated liquid and solid fuels aimed at gaining an understanding of the formation and destruction of intermediate products including dioxins and furans. The specific objectives are to acquire kinetic data on PCDD/PCDFs in spouted-bed and fixed-bed reactors in order to understand accepted formation mechanisms better; to elucidate the role of temperature residence time, precursor partial pressure, and particle size on rates and yields; to model these processes; and to identify the steps and parameters that require more intensive study. The GC/MS will greatly improve the ability to provide quantitative analyses of many samples. This in turn will enhance the likelihood that relationships to probable precursors can be better understood, and from that knowledge the role of certain operation and design parameters on products of incomplete combustion in actual incinerators can be addressed.
