Abstract:
     The present invention provides a new palladium catalyst and its preparation method. Said method includes the following steps: firstly, in situ synthesizing hydrotalcite lamellar precursor body containing palladium in carrier surface layer hole, then roasting at higher temp. to convert the lamellar precursor body into correspondent composite metal oxide, and using hydrogen gas to make reduction treatment so as to obtain the loaded type high-dispersion catalyst in which the palladium is highly dispersed into the surface of internal hole of the carrier. Said catalyst mainly is used in antraquinone hydrogenation process for preparing hydrogen peroxide by means of antraquinone method.
