Stability of B50 biodiesel added with glycerol ester additive based on palm oil oleic acid
نویسندگان
چکیده
Biodiesel in Indonesia is a mixture of Fatty Acid Methyl Ester (FAME) and diesel oil. Mixing FAME oil challenging since separated from at low temperatures. Changes the physico-chemical properties biodiesel during storage decrease quality due to dissolved oxygen, potentially damaging engine. Using glycerol ester (GE) as an additive can be alternative solution tackle that problem. This research examined stability GE-added biodiesel. As comparison, commercial diethyl ether (DEE) was used. The concentration added varied 1000, 2000, 3000 ppm while temperature 12, 25, 42℃. evaluated for three months by measuring acid value, viscosity, corrosion rate, water content. values of various types concentrations additives still meet SNI 7182-2015 standard (0.5 mg KOH g-1 sample) with value range 0.148- 0.392 sample. Kinematic viscosity had 3.12-3.58 cst, which also meets (2.3-6 cst). highest rate GE DEE first week, 0.447 0.261 mpy, respectively. Both B50 control addition 1000 same content on 18th day, 0.046%, this considered means adding maintain Overall, comply standard.
