SVD (KD)
Shows best performance in the first two beds. Unique resistance to high temperature deactivation.
SVNT (KD)
A highly active catalyst in the 2nd, 3rd, 4th and 5th beds. It has high conversion parameters for budget catalyst loading.
I К A-1-6 SVP
Super Vanadium Pentoxide. The catalyst operates in low temperature. It is intended for the substitution of basic cesium promoted catalysts. For use in 4 and 5 beds of DC-DA converters. May also be loaded in the 3rd bed and at the top of the 1st bed. Resistant to low temperature deactivation.
SVD (K-D, K)
It is used as ignition layer and/or in the last bed for converson increase. Reduction of SO2 emission (double absorption SAP) to 50-100 ppm.
SVD ( К -D, К ) SP
Super Cesium promoted. It is optimized to use in the last bed of a converter; maximum conversion is achieved. The SO2 emissions (double absorption SAP) are reduced down to 50 ppm.
