With performance comparable with that of imported products, our CHP78 series vanadium catalyst offers very high activity even under conditions of low temperature, high SO2, and low O2 level. Due to this, it is extensively used in stage 2, 3, 4, and 5 of the converter. Its catalyst performance is good even after the first absorption when SO2 level is low and O2 level is still very high.
The vanadium catalyst supports longer operation cycle because of its unique formulation and manufacturing processes, as well as the balance between activity and hardness. Its screening loss can also be reduced.
