QDB-02 is a new type of sulfur-resistant shift catalyst with dual functions of adsorption and shift. It has the characteristics of large pore volume, high strength, good physical and structural stability, etc. It can replace the main catalyst on the top of the catalyst bed or in the pre-shift furnace. It can not only effectively adsorb or remove harmful impurities or poisons such as tar, dust and arsenic in the process gas, but also protect the main catalyst from poisoning and extend its service life. At the same time, due to its suitable catalytic activity, QDB-02 can reduce the amount of the main catalyst and improve the economic benefits of the catalyst users.
