S101 catalyst is mainly composed of vanadium pentoxide and silicon dioxide. This vanadium catalyst is mainly used in the Section I lower part, Section II and Section III of the converter, with operating temperature 410 -620. The product is made of refined composite diatomite, with large specific surface area and porosity as well as low bulk density. Its bulk density is 14% -16% lower than that of similar products. The catalyst activity is 3%-5% higher than that of similar products. Other features include uniform strength, small deviation, and strong anti-chalking ability.
