According to the National Biodiesel Board, how much biodiesel was sold in the United States in 2006?

Biodiesel sales have steadily risen -- along with oil prices -- from 500,000 gallons sold in 1999 to 250 million in 2006.

Although biodiesel can be used in its pure form, it's usually blended with standard diesel fuel. Blends are indicated by the abbreviation Bxx, where xx is the percentage of biodiesel in the mixture.

What biofuel grade is pure biodiesel?

What process do facilities use to convert raw fat into biodiesel?

Raw fat or oil must first undergo a series of chemical reactions in order to become fuel. There are a few different ways to make biodiesel, but most manufacturing facilities produce industrial biodiesel through a process called transesterification.

Which part of the raw fat molecules make up biodiesel?

During transesterification, the triacylglycerol is transformed to form esters and glycerol. The esters that remain are what we then call biodiesel.

How much power does the average diesel engine lose when fueled by biodiesel?

In some engines, using biodiesel can cause a slight decrease in fuel economy and power. On average, there is about a 10 percent reduction in power. In other words, it takes about 1.1 gallons of biodiesel to equal 1 gallon of standard diesel.
