Specification: Black granular, with alumina as the carrier, with a loading capacity of 0.98~1.05wt.% for precious metals (Pd/Ru). The surface area of the catalyst is 360-380m2/g. The catalyst stack density is 0.69~0.72 cm3/g.

Application field: Used for deep removal of sulfides such as hydrogen sulfide, carbon disulfide, mercaptan, sulfide, thiophene, etc. from benzene. The catalyst, supported by high specific surface area alumina, can remove thiophene from benzene to below 0.01 ppm, with a sulfur capacity of over 0.8 grams of thiophene per kilogram  of catalyst.
