Abstract：
 The granular Ru/ZrxCe1-xO2 catalyst and its preparation process belongs to the field of water treating technology and environment functional material. The present invention discloses one kind of granular Ru/ZrxCe1-xO2 catalyst with active component Ru and carrier ZrxCe1-xO2 grain, and has high stability, easy separation from water, low production cost and other advantages. The preparation process of the granular Ru/ZrxCe1-xO2 catalyst includes dropping solution containing Zr and Ce into alkaline solution, filtering, dispersing the precipitate into deionized water, regulating pH value, adding adhesive, heating reflux, filtering, pelletizing the precipitate, drying, roasting to obtain ZrxCe1-xO2 grain, soaking ZrxCe1-xO2 grain inside RuCl3 solution, stoving, and final roasting to obtain the granular Ru/ZrxCe1-xO2 catalyst.
