DK-YTSR desulfurizer takes nickel and copper as the main active components, adds special additives, and uses special alumina as carrier and dispersant. DK-YTSR type sulfur protectant can effectively remove sulfide, but also remove chlorine and arsenic. The impurity content of sulfur, chlorine and arsenic in reforming or hydrogenating materials purified by the catalyst can be reduced to 0.5 PPM, 0.5 PPM and 1ppb, respectively.
