Is it possible to use biodiesel as a reference material

Using biodiesel and other alternative fuels and advanced technologies to reduce fuel consumption continues to strengthen national security and reduce transportation energy costs for businesses and consumers.

Biodiesel is produced in the United States and used in conventional diesel engines, directly substituting for or extending supplies of traditional petroleum diesel. Soybean biodiesel has a positive energy balance, meaning that soybean biodiesel yields 4. See USDA study for more details. Engines manufactured in and later must meet the same emissions standards, whether running on biodiesel, diesel, or any alternative fuel.

Selective catalytic reduction SCR technology in diesel vehicles, which reduces nitrogen oxide NO x emissions to near-zero levels, makes this possible. The emissions from engines using diesel fuel are comparable to those from biodiesel blends. Using biodiesel reduces life cycle emissions because carbon dioxide released from biodiesel combustion is offset by the carbon dioxide absorbed from growing soybeans or other feedstocks used to produce the fuel.

Air quality benefits of biodiesel are roughly commensurate with the amount of biodiesel in the blend. Learn more about biodiesel emissions. Biodiesel improves fuel lubricity and raises the cetane number of the fuel. Diesel engines depend on the lubricity of the fuel to keep moving parts from wearing prematurely. One unintended side effect of the federal regulations, which have reduced allowable fuel sulfur to only 15 ppm and lowered aromatics content, has been to reduce the lubricity of petroleum diesel.

To address this, the ASTM D diesel fuel specification was modified to add a lubricity requirement a maximum wear scar diameter on the high-frequency reciprocating rig [HFRR] test of microns.

This study analyses the possibility of using beef tallow biodiesel transesterified with ethanol, provided by Universidade Federal Fluminense, as a viscosity reference material for biodiesels. The behaviour of viscosity is analysed considering the estimated uncertainty of measurements for characterisation, homogeneity and stability.

The reason to study a transesterified biofuel with ethanol lies in the fact that it is easy to produce this fluid from sugarcane in Brazil. Viscosity Characterisation Stability Homogeneity Beef tallow biodiesel. Submitting the report failed.
