Provide high quality series of products for global customers
Product Description
1. Characteristics
The LJ series iron oxide is produced from α-type Fe using 2 and 3 valence iron salts and alkaline solution neutralization.2O3, H2O and y-type Fe2O3, H2O high-activity sponge-like mixed iron oxide is used as raw material, combined with pore-forming agents and binders to produce a water-resistant high-porosity iron oxide desulfurizer.
2. Applications
Mainly used for desulfurization in city gas, chemical energy, and other chemical industries where gas or raw gas is used, it can also be used for the removal of hydrogen sulfide in gases from other industries such as coal gas, coke oven gas, biogas, oil field gas, and waste gas.
