I am not a chemist, but I think that the oxygen  in a carbohydrate fuel 
is not considered to have "oxidized" anything at that stage. That would 
be a very confusing usage of the word "oxidize."

Instead, with the pyrolysis process, the atoms in the carbohydrate 
(biomass) are "disassociated" (freed from the other atoms) and are then 
able to enter into subsequent reactions which, in the case of O and H, 
they become H2O, in basically the same way and with  the same energy 
release as when H2 and O2 come together with a spark and make water.

I will accept the comments from the combustion experts.
