| Summary: | Biodiesel is one of the alternative fuels which are derived from straight or used
vegetable oils and animal fats. It is a biodegradable, renewable energy and clean
burning alternative. This paper presents a comparative study on efficiency of
conversion of waste oil and fat to biodiesel and the performance of diesel engine
using waste oil and fat biodiesel. The base-catalyzed transesterification method was
used to produce biodiesel from waste oils (waste palm oil, waste coconut oil and
waste sunflower oil) and fats (beef tallow, duck tallow and chicken fat). The
conversion of waste coconut oil (97%) and duck tallow (96.4%) to biodiesel
produced the highest yield. However, the conversion of waste palm oil (91%) and
chicken fat (94%) to biodiesel resulted in lowest yield. Short-term engine
performance tests were carried out on test diesel engine fuelled with waste oil or fat
biodiesel blends from B0 to B50. It was found that waste oil and fat biodiesel blends
showed a decrease in engine power output, brake horse power and mechanical
efficiency. Conversely, the specific fuel consumption increased with blending
percentage. While fueling diesel engine with waste coconut or beef oil biodiesel, it
resulted in lowest drop in engine power output and mechanical efficiency. Overall,
B20 biodiesel blend for all waste oils and fats resulted lower variation in engine
performance when fueling in diesel engine. It is recommended a further research
should be taken to improve the brake horse power, power output and reduction in the
specific fuel consumption. |
