供应Biodiesel Blends
Biodiesel can be blended and used in many different concentrations, including B100 (pure biodiesel), B20 (20% biodiesel, 80% petroleum diesel), B5 (5% biodiesel, 95% petroleum diesel) and B2 (2% biodiesel, 98% petroleum diesel). B20 is a common biodiesel blend in the United States.

Low-Level Blends
ASTM International develops specifications for conventional diesel fuel (ASTM D975). These specifications allow for biodiesel concentrations of up to 5% (B5). Low-level biodiesel blends, such as B5 are ASTM approved for safe operation in any compression-ignition engine designed to be operated on petroleum diesel. This can include light-duty and hey-duty diesel cars and trucks, tractors, boats, and electrical generators.

This specification covers 2% Biodiesel Fuel (B2). The blend shall consist of 2%
of Biodiesel Fuel (B100) Blend Stock and 98% Low Sulfur Diesel Fuel Oil (),
Ultra-Low Sulfur Diesel Fuel Oil (U) or Winter Premium Blend Fuel Oil.
II. REQUIREMENTS:
The Biodiesel Fuel (B100) Blend Stock used for producing B2 Fuel shall meet ASTM D 6751-03 Standard Specification for Biodiesel Fuel (B100) Blend Stock for Distillate Fuels prior to blending B2. Blending must take place at the refinery. The B2/DFO Blend shall conform to the requirements of ASTM D-975-04b Grades with the following modifications:

Note: B2/No. 2 Regular Blend ordered for use from April 1st to November 1st may he a Cloud
Point of 15 o
F maximum and a Pour Point of 10 o
F maximum if requested in writing by the purchaser.
B2 Low Temperature Blending: Blends shall be of No.1 and No.2 Premium at the proportions requested by purchaser. Blended diesel fuel oils shall meet the requirements of No.1 diesel fuel with the following modifications:


B2/ Winter Premium Diesel Fuel Blends
B2/ Winter Premium Diesel Fuel shall be conform to the requirements listed
below:

Lubricity – All blends shall meet the 520 micron maximum requirement specified in ASTM D975-04b. Lubricity additives shall be added to blends that fail the lubricity requirement. Testing shall be done to verify lubricity requirement is met.
III. SAMPLING: Samples shall be taken from the tanker at the time of delivery. Sample containers shall be one quart metal cans with tight-fitting screw tops lids.
IV. TESTING: Testing shall be according to test methods referenced in ASTM D-975-04b or other appropriate test methods.
