| 内容記述 | The diffusion processes of N_2, He, CO_2, C_2H_4 and C_3H_6 in a silver catalyst for ethylene partial oxidation have been studied with a steady state diaphragm cell method using an atomospheric flow system at 30?180℃, relating to ethylene oxidation. Three different catalyst surfaces were prepared as oxidized (S_<OX>), reduced (S_<red>) and treated with ethylene (S_<In>) on which the stable intermediate (In) were accumulated, compared among the effective diffusivities of the gases (De). The molecular diffusion process was achieved with N_2 and He for all the surfaces and at all the gases except O_2 on S_<red>. The De’s of CO_2, C_2H_4 and C_3H_6 on S_<In>. were higher than those on S_<red>, suggesting the contribution of surface diffusion on S_<In>. (In) works to increase the amount of isolated surface oxygen species which is available for the adsorption sites of CO_2, C_2H_4 and C_3H_6. This phenomena causes localization of the gases on the surface and change in their surface diffusion rate. | |||||
