Glycerine is not "removed" from VO when it is converted to biodiesel. There is actually no glycerine in VO. Just because it is a byproduct of the transesterification reaction does not mean it was "removed" from the feedstock VO.UFO said:I believe the "ring sticking" is caused mostly from incompletely burned fuel getting trapped and cooking in the rings. This is far less likely with biodiesel, as the sticky stuff (glycerine) has been removed in the fuel-making process.
I believe that the "ring sticking" is more related to the tendency for VO fuels to polymerize. Biodiesel also has a tendency to polymerize, though it does not appear to happn as rapidly as with VO. However, this depends greatly upon feedstocks and this is why Canola is noted as being superior to soy when used as fuel.
