Effect of acidity on the performance of a Ni-based catalyst for hydrogen production through propane steam reforming |
| 초록 |
Propane steam reforming (PSR) for the production of H2 was catalyzed by a NiO/K-AlSixOy catalyst synthesized with various Al/Si ratios. The effect of the Si/Al ratio on the acidity of the NiO/K-AlSixOy catalyst for PSR was investigated. NiO/K-AlSixOy gave a higher H2 selectivity and stability during PSR than NiO/K-SiO2 and NiO/K-Al2O3. X-ray diffraction, scanning electron microscopy/energy-dispersive X-ray spectroscopy, N2 adsorption/desorption, NH3, C3H8, and CO temperature-programmed desorption (TPD), temperature-programmed reduction, and temperature-programmed oxidation were used for catalyst characterization. The NH3-TPD results showed that the acid quantity and strength of NiO/K-AlSixOy changed significantly depending on the Si/Al ratio. With an increased Si/Al ratio, the densities of both weak and strong acid sites increased. PSR results showed that the NiO/K-AlSixOy catalyst exhibited much better stability than the NiO/K-SiO2 and NiO/K-Al2O3 catalysts. |
