英文摘要：

Supercritical CO2 can eliminate mass transport limitations in catalytic reaction with gases reactants and makes the scCO2 very attractive for improve the safety in laboratory and chemical industrial production. In this work, taking the reactions of hydrogenation, hydroformylation and oxidation as examples, recent research progress about catalytic reaction on the use of gaseous reactants with supercritical CO2 as reaction media were reviewed. Finally, the developing trends are discussed.
