Kinetics of Gas-Phase Reactions of Metallic Species Over Wide Temperature Ranges

研究正在进行中，以扩大金属化学的温度范围。还需要研究涉及金属氧化物和单卤化物的反应。这个更高的范围（高达1900K）需要设计一个伪静态光化学反应器（HTP），可以在没有壁干扰的情况下启动和监测反应。在这些壁面限制消失的实验条件下，可以使用快速流动技术（HTFFR），并使两种方法的交叉验证成为可能。准分子激光的加入将使从它们的化合物中光解生成广泛的金属成为可能。所考虑的反应涉及Mn， Ba, Cu， Al和Ca。这些元素在飞灰和煤烟中的存在是造成腐蚀污垢甚至粉尘爆炸问题的原因。相反，一些工业过程（如炭黑的产生，电子制造中的化学气相沉积）依赖于这些化学活动。这些新知识对工业实践的影响可能是巨大的。

Research is underway to extend the range of temperatures in which metal chemistry is understood. Also to be studied are the reactions involving metallic oxides and monohalides. This higher range (up to 1900K) requires the design of a pseudo static photochemistry reactor (HTP) where reactions can be initiated and monitored without wall interference. In these experimental conditions where the wall limitations disappear, the former, well understood, fast flow technique (HTFFR) can be used in addition, and the cross validation of these two methods become possible. The addition of an excimer laser would make possible the photolytic generation of a broad range of metals from their compounds. The reactions contemplated involve Mn, Ba, Cu, Al and Ca. The presence of these elements in fly ash and soot is the cause of problems of corrosion fouling or even dust explosions. Conversely, some industrial processes (e.g. carbon black generation, chemical vapor deposition in electronics manufactures) depend on such chemical activities. The impact on such new knowledge on industrial practice could be substantial.
