On the NiO/SiO〓 catalyst prepared by IM, the main hydrogenation product of MA was SA, the activity and selectivity were almost no relation with the nickel content and nickel species 3. Summarizing the characterization and activity evaluation of the catalysts, we concluded: On nickel based catalyst, when NiO was crystallite, and the Ni〓 that was prepared by reducing, hydrogenation of the MA could lead to SA but not to γ-BL; when NiO was cluster and had a properly interaction with the support, the Ni〓 prepared by reducing, could hydrogenate MA to SA then to γ-BL. When NiO cluster and crystallite were both existed on the catalyst, the hydrogenation products were mixture of SA and γ-BL, and the amounts of SA and γ-BL were related with the ratio of cluster and crystallite.

综合催化剂的表征和活性评价得出：当镍基催化剂上氧化镍以结晶态存在，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到丁二酸酐，丁二酸酐难以进一步加氢为γ-丁内酯；当镍基催化剂上氧化镍以簇团形式存在，与载体之间有适当的相互作用时，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到的丁二酸酐进一步加氢为γ-丁内酯；若催化剂上氧化镍既有结晶态又有簇团形式时，随二者含量比例不同而得到丁二酸酐和γ-丁内酯的混合物。

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).
