Oxidative coupling of methane over sodium-doped CaO catalysts prepared by the sol-gel methodOxidative coupling of methane over sodium-doped CaO catalysts prepared by the sol-gel method

摘要

Sodium-doped calcium oxide (Na/CaO) catalysts prepared by the sol-gel method (SGM) show relatively high performance for oxidative coupling of methane (OCM) compared with that prepared by impregnation method (IM). The difference between the performance of these catalysts for OCM seems to come from the difference in morphology and TPD profiles of these catalysts.
