炼油技术中的主要工艺是将石油的重质馏分裂化成轻质和有价值的烃。介质阻挡放电（DBD）反应器在常压低温下工作，是碳氢化合物裂解的最新方法之一，已成功用于裂解低碳分子。因此，本文以正十六烷作为重质烃，采用圆柱形DBD反应器（低温等离子体）进行了裂解反应研究。采用气相色谱-火焰离子化检测器和质谱检测器，研究了气体种类、外加电压和气体流速对气相色谱-质谱联用的影响。结果表明，甲烷对转化率和裂解率的影响均优于空气。此外，它已被证明，增加所施加的电压和工作气体流量提高转化率和裂化百分比。当电压为12 kV，甲烷流量为50 sccm时，转化率最高，为9.26%。在此条件下，产品的裂解率为84.34%。
The main process in oil refinery technologies is the cracking of the heavy fraction of oil into light and valuable hydrocarbons. Dielectric barrier discharge (DBD) reactors, working at atmospheric pressure and low temperature, is one of the newest methods for cracking hydrocarbons, which has been successfully used to crack low-carbon-containing molecules. Therefore, in this paper, the cracking of n-hexadecane as a heavy hydrocarbon fed by using the cylindrical DBD reactor (nonthermal plasma) has been investigated. We studied the effects of gas type, applied voltage, and gas flow rate quantitatively and qualitatively by using gas chromatography with flame ionization detector and mass spectrometry detector. Results showed that methane has better effects on both conversion and cracking percentage in comparison with air. Also, it has been shown that increasing the applied voltage and working gas flow rate enhances the conversion and the cracking percentages. The highest conversion percentage obtained was 9.26% when the applied voltage and methane flow rate were 12 kV and 50 sccm. In this condition, the cracking percentage obtained was 84.34% of the products.
