在这项工作中，氩气微波（2.45GHz）放电的等离子体化学在减压下对三种不同的烷烃（正戊烷，正己烷和正庚烷）的转化的影响进行了研究。光学发射光谱已被用于识别等离子体中产生的物种，并估计其气体温度。采用气相色谱、质谱、X射线衍射和FTIR光谱对反应产物中的所有化合物进行了鉴定和分析。已经发现微波功率和烃流速对转化率和选择性都有重要影响。主要的气体产品是氢气和乙烯。在低功率（100- 150 W）下，转化为氢气是相当有选择性的。然而，在高功率（> 300 W）或低烃流速下，乙烯已成为主要产物。在大多数情况下，获得的碳存款的重要部分被表征为无定形氢化碳膜。一些合理的机制解释的主要反应产物的形成进行了讨论。
In this work, the effects of the plasma chemistry of an argon microwave (2.45GHz) discharge at reduced pressure on the conversion of three different alkanes (n-pentane, n-hexane and n-heptane) have been studied. Optical emission spectroscopy has been used for identifying the species generated in the plasma and for estimating its gas temperature. Gas chromatography, mass spectrometry, X-ray diffraction and FTIR spectroscopy have been employed for identifying and analyzing all the compounds present as reaction products. Microwave power and hydrocarbon flow rate have been found critically to affect both conversion and selectivity. The main gas products have been hydrogen and ethylene. At low powers (100–150W) the conversion to hydrogen has been quite selective. However, at high powers (>300W) or slow hydrocarbon flow rate ethylene has resulted to be the major product. In most cases, an important fraction of a carbon deposit has been obtained which has been characterized as an amorphous hydrogenated carbon film. Some plausible mechanisms explaining the formation of the main reaction products have been discussed.
