Abstract:
In Korea, most resources for biodiesel production were imported from abroad. To find out domestic resources, the feasibility of biodiesel production from acid oil as a byproduct of the refining of vegetable oils and from waste lard as a byproduct of the leather making process with high content of free fatty acids (FFAs) was investigated. A process consisting of the esterification of FFAs by an acid catalyst followed by the transesterification of triglycerides by an alkali catalyst was examined. After a simple distillation process of biodiesel, the oxidation stability of acid oil biodiesel and waste lard biodiesel was 1.59 h and 1.83 h, respectively. The cold filter plugging point (CFPP) was 13. and 8., respectively. The oxidation stability of biodiesel was easily improved by antioxidants. However, the CFPP was not improved by additives. When waste lard biodiesel was blended with rapeseed oil biodiesel, the low temperature flow property of waste lard biodiesel was improved.
