An Investigation of the Initiation and Growth Mechanisms of Filamentous Coke over Iron, Nickel, Cobalt, and their Alloys

在这次调查中，将对铁、镍、钴及其某些合金与一系列二氧化碳、一氧化碳、甲烷、氢和水蒸气的混合物进行全面研究。研究的金属是真正有趣的，因为结果可以应用于从结构到不锈钢的各种实用材料。为本研究选择的气体也是真正令人感兴趣的，因为它们包括许多重要过程的反应物。所使用的分析方法将全面了解所涉及的详细机制。将使用的仪器组合将有助于确认这些系统的表面化学，并可能提供新的见解。实验将在不同的温度下进行，以更全面地了解碳丝生长的起始和生长机制。

In this investigation, a comprehensive study will be conducted of iron, nickel, cobalt and certain of their alloys with a range of mixtures of carbon dioxide, carbon monoxide, methane, hydrogen and water vapor. The metals studied are of real interest as results can be expected to apply to a variety of practical materials from structural to stainless steels. The gases chosen for this investigation are also of real interest because they include the reactants of so many significant processes. The analytical methods to be used will give a comprehensive view of the detailed mechanisms involved. The combination of instruments to be employed will serve to give confirmations and possible new insights for the surface chemistry of these systems. Experiments will be performed at different temperatures to give a more complete understanding of the initiation and growth mechanisms of carbon filament growth.
