摘要/Abstract

摘要：

废弃油脂不仅造成严重的环境污染,而且容易引发各种社会问题,因此加快对废弃油脂的综合利用势在必行。本文以大豆油作为废弃油脂替代物,在自制炬/反应器中开展旋转弧等离子体转化油脂制合成气研究,系统考察了水/大豆油质量比、输入功率和磁感应强度对大豆油转化过程的影响。研究结果表明,气体产物主要为CO、H₂、CO₂与烃类,CO与H₂最高可占气体总量的91.0%(体积)以上。水/大豆油质量比主要影响产物组成和能量转化效率,对碳气相转化率和合成气收率影响较小。增加输入功率,碳气相转化率可提高至98.5%,能量转化效率在17.9 kW时达到最大值72.9%。实验考察范围内磁感应强度对大豆油转化效果的影响很小,但可以起到保护阳极的作用。

Abstract:

Due to waste oil can cause serious pollution and various social problems, a study of its comprehensive utilization is imperative. In this study, soybean oil was used as substitute of waste oil and converted into syngas in a homemade rotating arc plasma reactor. Effects of water/oil mass ratio, input power and magnetic flux intensity on reaction performance were investigated. It was shown that the main product gas was CO and H₂, accounted for more than 91.0% (vol), as well as small amounts of CO₂ and hydrocarbons. Water/soybean oil mass ratio has a large impact on syngas compositions and energy conversion efficiency, but little impact on carbon conversion and syngas yield. Carbon conversion increased to 98.5% with the increase of input power and energy conversion efficiency reached the maximum of 72.9% at 17.9 kW. Magnetic flux intensity has a slight effect on results but it could protect the anode from erosion.

Key words: plasma, rotating arc, waste oil, soybean oil, pyrolysis, syngas, waste treatment
