S112 containing cesium vanadium catalyst

The product is suitable for the upper, third, fourth and fifth stages of the converter. Operating temperature 390 ℃ - 620 ℃.

S112 series of catalysts containing cesium and vanadium, is refined composite diatomite as a high-performance carrier, the use of new technology to alkali metal cesium, potassium compounds as additives, vanadium pentoxide and additives in the form of uniform solution, the full penetration To the carrier, and refined.

S112 low-temperature series of vanadium catalyst has a high activity level, in 370-620 ℃ throughout the temperature range with high activity, ignition temperature of 320 ℃, S112 series containing cesium vanadium catalyst has the following characteristics:

1. The reaction rate faster than ordinary sulfuric acid catalyst, especially for a period of imports of high concentrations of sulfur dioxide or oxygen, sulfur dioxide lower atmosphere conditions. And S108 compared to ordinary low-temperature catalyst, can effectively reduce the inlet temperature of about 20 ℃;

2. Has good low temperature (> 280 ℃) activity, for the converter four or five paragraphs, can significantly reduce sulfur dioxide emissions.

3. In the magazine content higher reaction atmosphere, and the more demanding transformation conditions, anti-powdering ability, long service life.
