John,
It says the "particles" are made of sand and calcium. The actual catalysts are
attached to the surface of the particle and the active catalyst compound is not
described (except to call them mixed oxides). I say "catalysts" because they
mention having both acid and base catalysts on the same particles.
"by creating a mixed oxide catalyst that has both acidic and basic catalytic
sites. Acidic catalysts on the particle can convert the free
fatty acids to biodiesel while basic catalysts can convert
the oils into fuel."
