FIELD: chemistry.

SUBSTANCE: present invention relates to catalysis. Invention discloses a carbon deposit resistant catalyst, a method of preparing said catalyst and use thereof. Carbon scale resistant catalyst consists of a carbon support, a metallic active component, a metallic additive I and a metallic additive II, where the metallic active component is platinum or palladium, the metallic additive I is zinc, or copper, or cobalt, and the metallic additive II is ruthenium or nickel, wherein in each type of metal components there is one and only one metal; content of metallic active component is 0.2-2.0% of weight of support, and weight ratio of metallic active component, metal additive I and metal additive II is 1:(1-10):(0.01-0.001).

EFFECT: three metals in the carbon deposit resistant catalyst of the present invention can form a multifunctional centre of catalytic activity, which can remove carbon deposits in location by hydrogenation while maintaining high catalytic properties of dechlorination, effectively suppress the formation of carbon deposits, and also significantly improve the stability and service life of the catalyst.
