Abstract

The mechanism of potassium‐catalyzed C/CO₂ reaction is studied by a temperature and concentration programmed reaction (TCPR) technique. The proposed redox mechanism contains three surface complexes: –CO₂K, –COK, and –CK. The oxide groups are the intermediates during C/CO₂ gasification. The completely reduced form, –CK, is the end product of catalyst reduction and is the precursor for K loss. The stoichiometries of these surface groups are confirmed by oxygen and potassium balances.
