Presentation on theme: "Biodiesel – General Definitions"— Presentation transcript:
1 Biodiesel – General Definitions Biodiesel is a domestic, renewable fuel for diesel engines derived from fats and oils such as soybeans and animal fats.Biodiesel can be used in any concentration with petroleum-based diesel fuel in existing diesel engines with little or no modification.Biodiesel is not raw vegetable oil!Biodiesel must be produced by a chemical process that removes glycerin from the oil.Biodiesel blend, n. -- a blend of biodiesel fuel meeting ASTM D 6751 with petroleum-based diesel fuel designated BXX, where XX is the volume percent of biodiesel.
2 Petroleum (Liquid Fuel) Picture We currently import over 50% of our petroleum needs - 70% by 2025.Once roughly half the oil has been extracted, it becomes harder – and more expensive – to get at the remainder.The key date is not when the oil runs out, but when production peaks, meaning supplies decline. The peak may come by about 2020.Proved Oil Reserves 2003This slide explains/shows our current situation of relying on petroleum to supply our transportation needs of gasoline and diesel.the current and future petroleum picture for which we relay on for about 95-97% of our current transportation needs and that as a nation we use approximately 20 million barrels of oil per day (world consumption = 80 million barrels).Point out that we are now importing about 55% of our total petroleum needs, that figure is expected to rise within the next 20 years to 70%, and that at $50 per barrel (average 2005 figure) we send over 365 billion dollars overseas for petroleum.Make the point that oil is a finite resource; that is, it will eventually run out someday and the question is when. The top picture shows
3 Biodiesel Properties & Attributes B100 - Energy content of #1, 8% less than #2High Cetane (avg. over 50)Sulfur freeCold flow - B2 the same as #2 petroleum dieselEnergy Balance (3.24 to 1)Biodegradable and Non-Toxic
4 Emissions Reductions with Biodiesel Blends Emission Type B B20 B2Total Unburned Hydrocarbons -67% -20% -2.2%Carbon Monoxide % -12% -1.3%Particulate Matter % -12% -1.3%Oxides of Nitrogen (NOX) % + 2%*** +0.2%“When considering the combined benefit of all these reductions, the small increase in nitrogen oxides (NOx) should not overshadow the net environmental gain with biodiesel use in North Carolina. Biodiesel is a viable part of the overall effort to improve our air quality.”B. Keith Overcash, PE, NC DE&NR, DAQ
5 Biodiesel Production 100 lbs. of fat or oil + 10 lbs. methanol catalyst 100 lbs. biodiesel (B100)10 lbs. of glycerinSoybeans (90-95% of current market), Waste Greases, Edible & Inedible Tallow, Cottonseed, Sunflower, Canola/RapeseedB100 Fuel Survey Results
7 ASTM D 6751 – Biodiesel Fuel Specification Fuel quality is of the utmost concern and importance to the biodiesel industry.ASTM D 6751 is the specification for biodiesel fuels irrespective of the feedstock source and/or processing method.Standard ensures safe operation in a compression ignition engine.
8 Biodiesel & Original Equipment Manufacturers (OEMs) B100 Must MeetASTM D6751 !!!Most OEM HQ’s have B20 experience:Won’t void warranty, but remember OEM’s don’t make fuel and therefore they won’t warranty fuel.Problems caused by the fuel are the responsibility of the fuel supplier.Many Engine Manufacturers Support Biodiesel Blends:John DeereCaterpillarCumminsDetroit DieselInternationalTestimonials for each of these companies available on the NBB website -

10 Biodiesel: Looking Forward Current Potential: 1.7 Billion gal/year5.5% of national on-hwy. DemandNear-Term Potential: (2015): 3.5 Billion6.8% of national on-hwy. demand in 2015Long-Term Potential: (2030): 10 Billion
