| 제목 | Role of CO2 on the Propane to Aromatics under the CO2 Stream over Ga-Pd(Pt) HZSM-5 Catalysts |
| 초록 | The conversion of light hydrocarbons into value added aromatic is one of the major challenges in the chemical industry. The key steps in this process are considered as the selective activation of C-H bond and the formation of C-C bonds through the dehydrogenation as an initial step. Such dehydrogenation step requires high temperature due to strong endothermic reaction, which subsequently gives serious coke problems. Thus, various metallo-zeolites such as Ga-ZSM-5 and Zn-ZSM-5 have been used for propane aromatization. In this work, Ga incorporated ZSM-5 was synthesized directly by one-pot synthesis method using microwave. And then, noble metals such as Pd or Pt were loaded by the impregnation. These synthesized catalysts were tested for propane aromatization under CO2 as a carrier gas. And it was observed CO2 participated in the RWGS reaction, which allowed to remove the formed hydrogen and attributed to higher activity and played a role as the hydrogen scavenger. |
