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.
