MIXTURES OF VEGETABLE OIL AND USED FRYING OIL AS FEEDSTOCK FOR BIODIESEL PRODUCTION IN THAILAND

บทคัดย่อ ( Abstract )

In this study, used frying oil was mixed with 3 fresh vegetable oils at various blending ratios (0.03- 0.20 v/v) in order to study the feasibility of the biodiesel production from the mixed oil feedstocks by KOH-catalyzed methanolysis and also examine the effect of used frying oil content in oil feedstock on the reaction. The methanolysis was carried out with fresh vegetable oils (coconut, sunflower, and roselle oils), used frying oil (palm oil) and the mixtures of fresh vegetable oils and used frying oil in order to compare the methyl ester content in biodiesel products. The results revealed that biodiesels could be successfully produced from mixed oil feedstocks and the used frying oil- to-fresh vegetable oil ratio of 0.03 v/v was required in order to produced coconut-used frying oil and roselle-used frying oil biodiesels having methyl ester content higher than the minimum (96.5%w/w) prescribed by European Standard EN 14214 (2008) and Thai biodiesel (B100) specifications. The used frying oil content in oil feedstock had the negative effect on the reaction which resulted in the reduction of methyl ester content in biodiesel products. This was due to the free fatty acid and water in used frying oil caused soap formation which interfered with the reaction. The measured properties of biodiesels produced from mixed oil feedstocks at blending ratio of 0.03 v/v met with Thai biodiesel (B100) specifications, with the exception of the slight lower methyl ester content and lower viscosity of the sunflower-used frying oil biodiesel and the coconut-used frying oil biodiesel, respectively.
