Li-doped MgO From Different Preparative Routes for the Oxidative Coupling of Methane

Li-doped MgO was prepared on different preparative routes and with different loadings. The catalytic activity was found to decay for all catalysts for 40 h time on stream. A detailed structural analysis of 0.5 wt% Li-doped MgO showed heavy losses of Li, reduced surface area and grain growth. A corre...

Zusammenfassung:Li-doped MgO was prepared on different preparative routes and with different loadings. The catalytic activity was found to decay for all catalysts for 40 h time on stream. A detailed structural analysis of 0.5 wt% Li-doped MgO showed heavy losses of Li, reduced surface area and grain growth. A correlation between these factors and the deactivation could not be found. The reaction temperature and the flow rate were found to be the main deactivation parameters.
