CATALYSTS FOR STEEL MANUFACTURING

FIND OUT MORE

Modern steel manufacturing relies on catalyzed processes

Ranido offers variety of catalysts for every catalytic process in steel manufacturing, beginning with production of reducing agents for iron ore reduction – syngas and coke.

Syngas production by steam reforming (SMR) as well as autothermal reforming (ATR) requires high quality Ni based catalyst. Our portfolio includes several types of catalysts for the syngas production, including pre-reforming catalyst.

Traditional reduction agent, coke, serves as efficient reductant too. Its production is utilized by coal gasification and catalysis plays irreplaceable part in treatment of exhaust gases from the coal gasification (NH3, H2S).  Ranido offers high quality nickel-based catalyst for ammonia decomposition.

Hydrogen sulfide and other sulfur compounds in exhaust gases are treated via Claus process. Our RCAT®-900X series of Claus process catalysts include both alumina and titania-based catalysts suitable also for desulfurization of natural gas prior the steam reforming. Another popular option for hydrogen sulfide treatment is Wet sulfuric acid process, producing sulfuric acid and high-pressure steam. Our vanadia-based catalysts are perfect choice for WSA process!

Our offer reflects increasing popularity of iron production by Direct reduction process (DRI), where iron oxides are reduced in shaft furnace using a gas containing high concentrations of CO and H2. Reducing gas for DRI process is often produced utilizing catalytic Midrex process. Major advantage of the Midrex process (low pressure reforming) is that feed consists of natural gas and spent gas from shaft furnace. Enrichment of natural gas with spent gas coming from shaft furnace is a modern way of recycling. Ranido offers series of catalysts tailored for Midrex process.

Every catalyst needs high quality support media. Our alumina balls of highest purity are designed to withstand hard conditions of catalytic reactors. Alumina balls, as well as ceramic balls come in various sizes – choose the perfect size for your application!

Catalysts for Claus Process​

Claus Process serves to remove sulfur compounds from natural gas or exhauste sour gas from coal gasification.

H2S + 3/2O2 →  SO2 + H2O

2H2S + SO2 →  3/n Sn + 2H2O

 

Ranido offers series of catalysts suitable for Claus process:

RCAT®-9003
TiO2 (extrudate)Titania based Claus catalyst, very high COS/CS2 hydrolysis rate
RCAT®-9004Al2O3 + Fe2O3 (balls)Promoted alumina catalyst, oxygen scavenger

Catalysts for Wet Sulfuric Acid Process (WSA)

Wet sulfuric acid process uses feed gas containing H2S to produce concentrated sulfuric acid. Wet catalytic oxidation of SO2 is a crucial step.

SO2 + 1/2O2 →  SO3

 

Increase the conversion of SO2 with our V2O5 based catalysts:

Catalysts for Pre-reforming and Steam Reforming

Syngas, reducing agent in steel manufacturing, is often produced by steam reforming of natural gas.

CH4 + H2O → CO + 3H2

CO + H2O → CO2 + H2

Catalysts for Midrex Process

Direct reduced iron (DRI) process has become a popular method for reducing iron oxides without melting. Reducing gas (H2 + CO mixture) is provided by the Midrex process.

Fe2O3 + 3CO →  2Fe + 3CO2

Fe2O3 + 3H2 →  2Fe + 3H2O

 

Check out our new catalysts for the Midrex process:

Catalysts for Ammonia Decomposition

Ammonia decomposition catalyst is necessary both for Claus process and coal gasification to protect the atmospheric environment and prevent the equipment from corrosion.

NH3 → 1/2N2 + 3/2H2

2HCN + 2H2O + O2 → N2 + 3H2 + 2CO2

 

RCAT®-3000 is designed for the extreme conditions in NH3 decomposition furnace:
