Selectivity Studies of Hydrocarbon Reactions Over Supported Metal Catalysts

考察了影响负载型金属催化剂上小分子烃反应选择性的因素。各种技术被用来探测碳氢化合物与催化剂表面的相互作用，包括微量热法、程序升温反应光谱、同位素示踪研究、红外和激光拉曼光谱、穆斯堡尔光谱、磁化率、核磁共振、电子显微镜和反应动力学。小分子碳氢化合物的活化是催化活性研究的主要领域之一。它在液体燃料生产和许多化学过程中都有应用。了解影响选择性的因素是设计过程控制策略所必需的。

Factors responsible for determining selectivity in the reactions of small hydrocarbons over supported metal catalysis are investigated. A variety of techniques are used to probe the interactions of hydrocarbons with the catalyst surface, including microcalorimetry, temperature-programmed reaction spectrometry, isotopic tracer studies, infrared and laser Raman spectroscopies, Moessbauer spectroscopy, magnetic susceptibility, nuclear magnetic resonance, electron microscopy, and reaction kinetics. The activation of small hydrocarbons is one of the main areas of active research in catalysis. It has application to liquid fuels productions and many chemical processes. A knowledge of the factors influencing selectivity is necessary to permit design of process control strategies.
