摘要
The direct conversion of methane without an oxidant is an attractive approach to increase carbon efficiency. However, the reaction must be engineered appropriately. Herein, we propose a methane to olefins, aromatics, and hydrogen (MTOAH) system in which methane activation is promoted by co-feeding hydrocarbons generated from the Mo/HZSM-5 surface. The intentional separation of the catalyst and the gas-phase reaction at different temperatures (700 °C and 1020 °C) enables active and stable methane conversion via periodic reactions and regenerations. The linkage between MDA and MTOAH using 6Mo/HZSM-5 (30), which notably contributed to increasing the C2 production in MTOAH, was stabilized with 8.2% methane conversion during 49.5 h of the periodic CH4 reaction-H2 regeneration cycle. This study provides a new direction for achieving the efficient and carbon-neutral conversion of methane into useful chemicals.
