摘要:

分别采用空气、氩气大气压介质阻挡放电(DBD)等离子体对重油进行了处理。对经空气DBD等离子体处理后的重油进行粘温特性分析,发现重油粘度升高,流动性变差。红外光谱和四组分分析结果表明重油的重质组分含量升高,重油胶体体系被破坏,同时生成大量刺激性气味气体。为了便于分析气态产物的成分和含量,采用大气压氩气DBD等离子体处理重油并收集气体产物。气相色谱分析发现生成气中含有大量C1-C5的烃类和一定量氢气,其中氢气和甲烷含量占生成气的70%以上。实验结果表明重油在等离子体作用下既发生裂解又发生聚合反应,既生成低碳烃类,本身的流动性也变差。

Abstract:

Heavy oil was treated in dielectric barrier discharge (DBD) plasma reactor with air and argon used as the work gas respectively. When air was used, the oil became more viscous. Results from Fourier transform infrared spectroscopy measurement and the SARA analysis showed that the oil colloidal system was destroyed, a lot of gas was produced, and heavier components (Resin and asphaltene) left in oil. To make the analysis and explanation easier, argon was used as work gas. Gas chromatography (FID and TCD) was used to analyze the gas production, there were lot of C1−C5 hydrocarbons, and H2 was also of great concentration. Total content of hydrogen and methane is more than 70% of gaseous product. This showed that the cracking of heavy oil occurred. Heavy oil mobility was deteriorated by plasma, this indicated that polymerization reaction occurred as well as heavy oil was cracked.

Key words: Dielectric barrier discharge plasma, Air, Argon, Heavy oil
