Abstract
The thermal stability and an 80 h life test over nickel-based catalysts for CH4/O-2 to syngas reaction were investigated by flow-reactor, XPS, XRD and AAS analysis. The results indicate that the introduction of Li and La not only stabilized the support gamma-Al2O3 phase, but also suppressed the sint ering and loss of nickel, and in addition, enhanced the ability to suppress the carbon-deposition over NiO/Al2O3 during the high-temperature reaction.
