A prospective biodiesel user (waste management contractor) operates a fleet
already fitted with catalytic converters. Can anyone please point to an
authoritative reference which confirms that the fuel and the device are
compatible? Obviously the workers are in close proximity to the tailpipe
sulfur is the primary killer of cat converters. b100 has no sulfur.

I don't know why he would have cats on a fleet before he secures
the type of fuel supplied with 100% certainty. Even low sulfur
fuel binds up the catalyst in a converter, quickly rendering it
ineffective.
However, having a fleet that is fueled without fail from but one
source yields the

For Gasoline engines...
Sulfur in fuel do not bind the catalyst in the converter.
They (Sulfur oxides) compete for the active sites on the
catalyst.
There are only so many active sites and if the fuel
has high sulfur then more of these sites that could

Does anybody have any experience using biodiesel made from
a drying oil like linseed, tung, etc.? I know it's risky using them
as SVO (polymerizing on cylinder walls), but how about the
esters?

Ken,
You will find that hydrogenation of drying oils removes most, if
not all of the polymerization problem you refer to. This is
largely dependant upon the degree of hydrogenation.
Alkyl esters retain many of the properties of the original
feedstock, but not all.
