| 제목 | Effect of Gallium modification methods and Regeneration on Co-aromatization of Methane and Propane over Gallium-modified ZSM-5 catalysts |
| 초록 | Methane, the major component of shale gas, is well known for its chemical inertness and its direct transformation to value-added products such as BTX proves to be greatly challenging. Non-oxidative methane aromatization requires high temperature(~700 oC), and the extreme reaction condition leads to practical limitations such as severe catalytic deactivation. The use of propane as a co-reactant lowers the thermodynamic barrier and the co-aromatization of methane and propane is feasible at lower temperatrue(~550oC). In this study, Ga-modified ZSM-5 catalysts were prepared by different methods(wetness impregnation, hydrothermal synthesis) and their performance in co-aromatization was investigated. Regeneration experiments were also carried out and each catalyst, which turned out to display distinct catalytic behavior, was characterized by XRD, BET, and Solid-state NMR. |
