GC-MS for Kinetics, Catalysis, and Reaction Engineering Research

这项提案要求资金购买GC-MS系统，用于密歇根大学Phillip Savage教授和三名合作PI指导的研究项目。这些研究人员在动力学和催化方面有着共同的兴趣。配有质谱仪(MS)检测器的气相色谱仪(GC)是一种非常强大的分析仪器。GC可以在复杂的反应产物混合物中分离单个样品成分，而MS提供洗脱化合物的通用和特异性检测。GC分离和MS检测相结合，可以对复杂的反应产物光谱进行完全解析、定性鉴定和定量分析。这一特点使得GC-MS在动力学、催化和反应工程的实验研究中具有非常重要的价值。正在进行的项目在工业应用中产生了更广泛的影响。将利用GC-MS进行的研究项目包括：探索利用高温水作为不同工业化学品的环境友好反应介质；减少五氯苯酚生产过程中氯化二苯并对二恶英的生成；开发高活性催化剂和选择性催化还原NOx的新策略；阐明石油沥青质的老化机理；防止海底输油管道结蜡。拟议的活动预计将促进发现和理解，同时促进教学、培训和学习。

This proposal requests funds to purchase a GC-MS system for use on research projects directed by Professors Phillip Savage and three co-PIs at the University of Michigan. These investigators share common interests in kinetics and catalysis. A gas chromatograph (GC) equipped with a mass spectrometric (MS) detector is an extremely powerful analytical instrument. The GC can separate individual sample constituents in a complex mixture of reaction products, and the MS provides both universal and specific detection of the eluting compounds. The combination of separation by GC and detection by MS allows the complete resolution, qualitative identification, and quantitative analysis of even complex reaction product spectra. This feature renders GC-MS invaluable for experimental research in kinetics, catalysis, and reaction engineering. The ongoing projects have broader impacts in industrial applications. The research projects for which the GC-MS would be used include exploring the use of high-temperature water as an environmentally benign reaction medium for different industrial chemistries, reducing the formation of chlorinated dibenzo-p-dioxins during the production of pentachlorophenol, developing high-activity catalysts and novel strategies for selective catalytic reduction of NOx, elucidating the aging mechanism for petroleum asphaltenes, and preventing wax deposition in sub-sea oil pipelines. The proposed activities are expected to advance discovery and understanding while promoting teaching, training, and learning.
