Research Progress of La2O3 Catalysts for Oxidative Coupling of Methane
The oxidation coupling of methane(OCM)reaction can directly produce ethylene,which has significant potential to replace traditional production mode of ethylene from petroleum cracking.It also can reduce the dependency of petroleum resources,which is extremely important for ensuring our energy security.Among OCM reaction,the La2O3 catalysts show excellent catalytic performance and low temperature activation characteristics,which attracts the attention of many researchers.In this paper,aiming at the oxidative coupling reaction of methane,the influencing factors on the activity of lanthanum oxide catalyst,the key points and improvement measures to improve the catalytic performance of lanthanum oxide were reviewed,being helpful to promote the further development of methane oxidative coupling process based on lanthanum oxide catalyst.
