(2):S109 Broad Temperature Type of Sulfuric Acid Catalyst

Type S109 catalyst’s operation temperature is much wider, which can be continuously operated in the range of 390 ℃-620 ℃. The activity of low temperature and the performance of heat-resistant is much better than traditional medium broad temperature type of catalysts. This catalyst can replace composition using of S101 series and S108 series in double-absorption plants, and much easier in loading and refilling of catalysts.

Attention:

S101 can be used alone in every bed of a converter.

To reduce the working temperature and increase the final exchange rate, S101 and S108 may also be used together. Generally S108 is loading at 1/3 or 1/2 top of the first bed or the second bed. In the other parts S101 is used.

the loading quantities of round or petal type should accord with the column type

the converter should enlarge 10% to 15% when using round or column type.
  
3:S106Anti-Arsenic Type Catalyst
Type S106 catalysts suit for resource gas from roasting gas contained high Arsenic trioxide (As2O3) 5-50mg/m3 or smelting gas to produce sulphuric acid by contact process. The resistance to poison is good, and its resistance to Arsenic is three times or four times than traditional types of catalysts, and save losses of vanadium 10-30%, and can absorb Arsenic 1 or 2 times more.
