Production and Property Improvement of Biodiesel from Waste ...

Antineutrino energy spectrum unfolding based on the Daya Bay measurement and its applications

The 18th European Biomass conference and Exhibition

作者： park j.-Y. kim D.-k. park s.-c. lee j.-s.

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 by-product of the refining of vegetable oils and from waste lard as a by-product 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.

A diesel engine for tractor was tested for 250 hours of durability with biodiesel fuel of 100%. An engine test cycle was designed based on the IsO test code of off-road vehicle. Eight test conditions, combination of three engine speeds and eight engine loads, were applied to the engine endurance test, and the engine was operated for eight hours in a day. Power output, fuel consumption rate, exhaust gas quality and particulate matter （Pm） were measured and discussed. For the extensive 250 hours of the tractor diesel engine endurance test no significant changes of power output, fuel consumption rate, exhaust gas quality and Pm were monitored and authors could not find any difference in the engine patterns of the two fuels of BDF100 and light oil. During all the engine endurance test conditions, no abrupt stopping was encountered but because of temperature down by the cold season the endurance test could not carried out for some periods. Pms were collected and the average F＇m was 0.027 g/kw which was far below than Tier 4 diesel engine Pm of 0.3 g/kw h defined by Us EPA Pm of the diesel engine clas,;. Overall even 100% biodiesel can be an alternative fuel for light oil for diesel engine operation with some considerations for cold sea：son use.
