Study on the Mechanism of Heterogeneous Catalysis (2) <br>—The Relative Catalytic Activities of Fe, Co, Ni, Cu, Ag and SiO2 in the Carbon Catalyzed Gasification Reaction

Abstract

This is a validation article. The experimental results such as the relative catalytic activities of Fe, Co, Ni, Cu, Ag and SiO2 poisoning in the carbothermic reduction iron oxide show that the Electron Cyclic Donate-Accept Catalytic Mechanism-ECDAM or Electron Obital Deformation-Recovery cycle Catalysis Mechanism-EODRM are credible, and the Chemical Reaction Model Catalytic Cyclic Mechanism-CRMM such as the Oxygen Transfer Mechanism-OTT that is long and wide spread in the literature is completely unreliable. Because the Fe, Co, Ni, Cu, Ag were unlikely to react cyclic oxidation—reduction reaction with the carbon in the carbon reduction reaction tank.
