| 英文摘要 | Catalyst durability is one of the major problems hindering the commercialization of partial oxidation of methane (POM) for syngas production. We report that a Pt/MgAl2O4-HS catalyst with the MgAl2O4-HS support being synthesized via hydrolysis solvothermal (HS) method demonstrates high stability for POM during a 500 h life testing at 900 degrees C without detectable coke formation, while a Pt/MgAl2O4-CP counterpart in which MgAl2O4 was prepared by an optimized co-precipitation (CP) method exhibits continuous deactivation accompanied by coking. Using a suite of characterizations lncluidng BET, H-2 chemisorption, XRD, STEM, TEM, TG/DTA and TPD of NH3 and CO2, we reveal that the high catalytic durability of the Pt/MgAl2O4-HS is due to the spinel surface of MgAl2O4 HS that can efficiently stabilize Pt against sintering. The Pt/MgAl2O4-CP, however, has defect Al2O3 or MgO-like species on the MgAl2O4-CP surface, inhibiting its capability to stabilize Pt. We confirm that the POM reaction undergoes a combustion-reforming pathway by monitoring the temperatures and gaseous product compositions along the catalyst bed. These results provide guidance for rational design of a longevity catalyst for POM process. |
