摘要
The effects of heating rate and particle size on degradation of polyethylene to oils in supercritical water were investigated with a 125mL autoclave.The results show that with the increase of heating rate,the yield of oil increases and that of gas decreases.In addition,the fraction of heavy hydrocarbons and the ratio of 1-alkene to n-alkane are relatively high under higher heating rate.More gas products and alkenes are produced using small particle polyethylene as raw material.
