Product description

PS-3-INS catalysts are fused catalysts. Two types of catalyst are available: in oxide form (PS-3-INS) or prereduced (PS-3-INS-R). The catalyst's composition includes: K2O, Al2O3, MgO, CaO, SiO2, and iron in oxide or metallic form depending on catalyst type. The catalyst's active state is obtained through a reduction process.

The main properties of iron catalysts are:
  • high and stable performance,
  • selectivity,
  • high mechanical strength,
  • low flow resistance,
  • long lifespan.

Application and use

The process of ammonia synthesis from hydrogen and nitrogen.

Packing and transport

The iron catalyst is packed in polyethylene bags placed in 60 litre drums, tightly sealed for protection against moisture and contamination. Different packing is permissible upon agreement with the customer, provided it will secure the product equally well as the type mentioned above.

The iron catalyst is not a hazardous product according to ADR, RID and IMDG regulations.
