棕榈油生物柴油低温流动性的改进及其对氧化稳定性的影响
Improvement of cold flow property of palm oil biodiesel and its impact on the oxidation stability
摘要
Abstract
The cold flow property and oxidation stability of palm oil biodiesel (PME) were investigated and the results indicated that PME exhibits favorable oxidation stability and poor cold flow property.Therefore,different methods (blended with-10# diesel,methyl oleate and rapeseed oil biodieselwith different volume ratio) were used to improve the cold flow property of PME.The impacts of improved methods on the cold flow property and oxidation stability of PME were investigated by Rheometer and Rancimat method,respectively.Experimental results suggested that the gelation point of PME is decreased but the oxidation stability become worse when PME blended with methyl oleate.When the volume fraction of PME is between 5％～20％,the gelation point of PME and-10# diesel blend is lower than-10 ℃ and the induction period is larger than 20 h.When the volume fraction of PME is lower than 40％,the gelation point of PME and RME blend is lower than 0 ℃ and the induction period is larger than 6 h.关键词
