<div>Oxidation during pyrolysis:<br>
<br>
Not a reference, but a statement and question: When a
carbohydrate molecule (containing O and H and C) is broken
apart by heat (which is the process of pyrolysis), what
happens inside the molecule is not totally understood. Is it
not possible that a carbon atom that is linked to an oxygen
atom (and to many other atoms) could not be shedding the other
atoms and the C + O are never separated? That would result
in a molecule of CO that is NOT from the combination of C with
O, and therefore the C was not oxidized. The C was already
with the O.<br>
<br>
The "atomic scientists" can discuss that possibility. I
leave it as CO being present as a result of pyrolysis, and not
necessarily because some "free standing" "liberated" atom of O
was then joined with an atom of C.<br>
