Effect of Al2O3 Phase Transformation in Plasma Catalysis of CH4 Activation |
| 초록 |
Direct methane activation was performed over θ, γ and α Al2O3 phase in hybrid plasma-catalytic system using a dielectric barrier discharge (DBD) reactor powered by AC sinusoidal current performed at plasma induced temperature. Phase transformation in Al2O3 has negligible effect over CH4 (10% in Ar) conversion but has significant effect on the selectivity of C2 hydrocarbons. Using γ Al2O3, mesh size of the catalyst ranging 1.70 mm to 0.25 mm was investigated in DBD reactor at 6kV and 3kHz. The conversion of methane on Al2O3 catalysts increased as the mesh size of the catalyst decreased. Product distribution of C2 hydrocarbons was successfully tuned by changing the mesh size of catalysts. |
