DESULF- Gas desulfurization by steel industry side streams

​ZnO pellets are used as sulphur adsorbents for synthesis gas from biomass gasification, coking gas from steel production and biogas. Due to the high price of adsorbing pellets based on primary ZnO powders, e.g., the gasification process is not always economically viable. Simultaneously, large amounts of Zn-containing side streams are generated in steel industry, with poor profitability of recycling. In the worst case, the side streams are disposed as hazardous waste, which is very costly. Read more about project…

Solutions to be brought to the market
