Abstract

Oxidative Coupling of Methane (OCM) is a promising reaction to produce ethylene from natural gas in one step. Basic oxides are known to be effective catalysts for OCM. Especially, lanthanum oxide has high activity for OCM. Therefore, we investigated modifying lanthanum oxide with alkali-earth metal cation for high active/selective OCM catalyst. Among them, Ca and Sr improved the activity. It was inferred that the improvement of activity derived from enhancement of both basicity and oxygen defect on catalyst surface.
