Comparison To Biodiesel
Based on its feedstock green diesel could be classified as biodiesel; however, based on the processing technology and chemical formula green diesel and biodiesel are different products. The chemical reaction commonly used to produce biodiesel is known as transesterification. Vegetable oil and alcohol are reacted, producing esters, or biodiesel, and the coproduct, glycerol.
When refining vegetable oil, no glycerol is produced, only fuels. Refined diesel can be produced that is chemically identical to diesel fuel and does not have the problems specific to transesterified biodiesel. Any blending ratio can be used, and no modifications or checks are required for any diesel engine.

Famous quotes containing the word comparison:
“Certainly there is not the fight recorded in Concord history, at least, if in the history of America, that will bear a moment’s comparison with this, whether for the numbers engaged in it, or for the patriotism and heroism displayed.”
—Henry David Thoreau (1817–1862)
