Theactivity and the number of surface oxygen of a series of vanadium oxide catalysts were studied by TPD equilibrium and TPD/MS technique.
应用此法和TPD/MS实验技术同时测定了一些钒系催化剂的表面活性氧的活性和供氧数目。
TPD MSand TPSR MS results indicate that COcan suppress the adsorption of CO2 on the sites, which bring about the reverse water gas shift reaction and hence promote the selectivity of methanol.
TPD-MS和TPSR-MS结果表明,CO能抑制催化剂表面起逆水汽变换作用的活性位对CO2的吸附,从而提高了CO2加氢合成甲醇的选抒性。
