BIODIESEL EMISSIONS VS DIESEL

Biodiesel_fossil_comparison_table2

Biodiesel is the first and the only alternative fuel to have a complete evaluation of emission results and potential health effects submitted to the U.S. Environmental Protection Agency (EPA) under the Clean Air Act Section 211(b). These programs include the most stringent emissions testing protocols ever required by EPA for certification of fuels or fuel additives. The data gathered complete the most thorough
inventory of the environmental and human health effects attributes that current technology will allow.

BIODIESEL EMISSIONS COMPARED TO CONVENTIONAL DIESEL
Emission Type B100 Biodiesel B20 Petro-diesel
Total Unturned Hydrocarbons -93% -30%
Carbon Monoxide -50% -20%
Particulate Matter -30% -22%
Sulfates -100% -20%
PAH (Polycyclic Aromatic Hydrocarbons) -80% -13%
nPAH (nitrated PAH’s) -90% -50%
Ozone potential of speciated HC -50% -10%
PRODUCT UNIT GROSS CV % OF PURITY NET CV SPECIFIC GRAVITY EFFECTIVE CV
(1) (2) (3) (4) (5) = (3)X(4) (6) (7) = (5)x(6)

* Net Calorific Value = Gross Calorific Value X %Gross Calorific Value.
# Effective Calorific Value = Net Calorific Value X Specific Gravity.

The Effective Calorific Value of Bio-diesel is slightly more than High Speed Diesel, so in terms of power output and fuel consumption, Bio-diesel performs same as High Speed Diesel.
