The degree of hydrogenation of methyl benzoate might be controled by adding the promoters and changing the nano-size of ZnO. For hydrogenation of methyl benzoate to benzaldehyde, the active-structure of a catalyst should be modified to decrease the absorption of benzaldehyde on the surface of it, because benzaldehyde absorbed is hydrogenated easily. Using 30-40%ZnO/γ-Al〓O〓 or Li-30%ZnO/γ-Al〓O〓, a higher selectivity to benzaldehyde is obtained. Hydrogenolysis of methyl benzoate to toluene or benzene is carried out effectively using a catalyst modified. For instance, 45.3% selectivity to benzene and 100% conversion of methyl benzoate at 420℃ was obtained over 10%ZnO/MCM-41 with the nano-size particles of ZnO (2.4nm).
