Hydrogen reduction
WebMost oxidation-reduction (redox) processes involve the transfer of oxygen atoms, hydrogen atoms, or electrons, with all three processes sharing two important characteristics: (1) they are coupled—i.e., in any oxidation reaction a reciprocal reduction occurs, and (2) they involve a characteristic net chemical change—i.e., an atom or … WebHydrogen was used as the reduction gas, whereas nitrogen was used as fluidization gas at start-up (till the desired bed temperature was obtained) and at shut-down. Nitrogen and hydrogen gas was supplied to the fluidized bed using separate mass flow controllers.

The balanced reduction half reaction is as follows: 2 H + + 2 e − → H 2 There are two hydrogen atoms on each side, and the two electrons written as reactants serve to neutralize the 2+ charge on the reactant hydrogen ions. Again, the overall charge on both sides is zero.
