Abstract To evaluate the quality of biodiesel (B100) fuel being produced in the United States, research staff members at the U.S. Department of Energy's National Renewable Energy Laboratory conduct periodic B100 quality surveys. In order to be a legal fuel and qualify for tax credits, B100 must meet ASTM International D6751 specifications. For the 2007 survey, samples were collected directly from U.S. producers between April and November 2007. The samples were compared against the National Biodiesel Accreditation Program (BQ-9000) critical properties (except sulfur) and metals using ASTM International test methods. These properties are a subset of the full ASTM D6751 B100 requirements. Samples were requested from all 107 producers, as determined from the National Biodiesel Board at the start of the survey. The 56 producers that provided samples represented 52% of the producers in the marketplace. Of the other 51 producers, 38 did not have product available, 7 did not respond, four declined to participate, one had shut down its plant to perform upgrades, and one no longer existed. The samples were tested for properties deemed critical for engine operation: oxidation stability, flash point and alcohol content, cloud point, water and sediment, acid value, and free and total glycerin. They were also analyzed for the following elements: phosphorus, sodium, potassium, magnesium, and calcium. These elements are potent poisons for advanced emission control equipment.
