Outline of Final Research Achievements

To produce a biofuel alternative to low sulfur fossil fuel oil from trap grease, which is one of the lowest quality waste oils/fats, we developed the following two technologies for bio-fuel-oil (BFO) recovered from the trap grease using a low-quality waste heat. The fist one is a meltcrystallization technology for removal of saturated fatty acids and their glycerides. The other is a blending technology for dissolving BFO into A-Type Fuel Oil (AFO), which is the low sulfur fossil fuel oil. In both technology developments, we got new scientific and engineering findings through various experiments using their model systems. We concluded that the blending technology was able to meet the domestic fuel standard. Furthermore, we investigated BFO and exhaust gas during combustion of mixtures of AFO and BFO in terms of hazard and emission of air pollutants. Finally, we suggested the appropriate blending ratio of BFO to AFO with regarding to stable and safe use of BFO.
