FIG. 2 is a rear and bottom perspective view thereof;
FIG. 3 is a front elevation view thereof;
FIG. 4 is a rear elevation view thereof;
FIG. 5 is a left side elevation view thereof;
FIG. 6 is a right side elevation view thereof;
FIG. 7 is a top plan view thereof;
FIG. 8 is a bottom plan view thereof;
FIG. 9 is a perspective view thereof, shown in an alternative position; and,
FIG. 10 is an enlarged view of detail “10” identified in FIG. 1.
The even broken line showing of two door panel straps depict environmental subject matter and forms no part of the claimed design. All other even broken lines depict portions of the round shaped baby play mat that form no part of the claimed design. The dash dot dash lines in FIGS. 1 and 10 are for the purpose of illustrating the boundary of the enlarged view and form no part of the claimed design.

Abstract: 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 Al2O3 microspheres, 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 H2, 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.
