%X The synthesis of dimethoxymethane(DMM) by selective oxidization of methanol over the catalyst rhenium supported on ZrO2 in a fixed-bed reactor was investigated.It was found that higher temperature may promote the conversion of methanol but reduce the selectivity of DMM.The loading of rhenium on the catalyst exhibits a significant influence on methanol conversion and a maximum methanol conversion is obtained at a rhenium loading of 1.64%.XPS,H2-TPR and NH3-TPD suggested that ReOx/ZrO2 acts as a bifunctional catalyst in the reaction: the ReOx supported on ZrO2 is able to oxidize methanol,and then the reduced active sites contribute to the condensation of HCHO and methanol to form DMM.
