A process for preparing a catalyst comprising palladium supported on a carrier via a layered precursor, comprising the following steps: (1) synthesis of hydrotalcite layered precursor which comprises promoting metal element and aluminium on the surface of the carrier of A1Omicrospheres, the atoms of the promoting metal and aluminium being highly dispersed by each other and bonded firmly to the carrier due to the crystal lattice positioning effect of the hydrotalcite crystal; (2) introduction of palladium into the carrier through impregnation; (3) drying; and (4) calcination and reduction with H, the hydrotalcite layered precursor being converted into a composite oxide which consists of oxides of the promoting metal and aluminium, and the promoting metal element and aluminium being highly dispersed by each other and being able to separate and disperse the mainly active palladium element loaded later. The process has the advantages of improving the catalytic performance of the catalyst, enhancing the stability of the catalyst, and achieving the object of reducing the consumption of the precious metal-palladium.
