Catalysts: PS-3-INS, PS-3-INS-R series
Application
The PS-3-INS and PS-3-INS-R catalysts are designed for synthesis of ammonia from hydrogen and nitrogen.
Characteristics
The PS-3-INS (oxide form) and PS-3-INS-R (pre-reduced form) are alloy catalysts. The main component of the catalyst is magnetite and promoters. The pre-reduced catalyst contains metallic iron. Promoters ensure high activity of the catalyst, good thermal stability as well as resistance to overheating.
