V201-M (Equal to VK38 of Topsoe, XLP110 of MECS, O4-110/O4-111 of BASF)
V201-M is manufactured by unique method, which is resulted in the highly dispersed active V2O5 species on the surface of V201-M that has high specific surface area and high pore volume. The activity of V201-M is excellent over a wide range of operating conditions, which is suitable for all beds of any SO2 converter. The continuous operation temperature is in the range of 400 ~ 630 oC.

V208-M (Better than VK48 of Topsoe, XLP110 of MECS and O4-111 of BASF)
V208-M has higher V2O5 than V201-M, and is particularly suitable for Bed 3 of converters, where the process gas contains significant amounts of SO3.

V212-M (Equal to VK59 / VK69 of Topsoe, SCX-2000/Cs110/XCs120 of MECS and O4-115/O4-116 of BASF)
V212-M is a caesium catalyst, which contains much higher caesium than that of V208-M, and it shows unmatched high activity throughout the entire operating temperature. When V212-M installed on the top layer of the first bed, it can make the continuous operation temperature down to 370 oC and still maintains high SO2 conversion. When V212-M installed in Bed 4 or Bed 5, it can greatly reduce SO2 emissions and increase production rates.
