Steel Converter Slag as an Oxygen Carrier—Interaction with Sulfur Dioxide
نویسندگان
چکیده
Steel converter slag, also called Linz-Donawitz (LD) has been considered as an oxygen carrier for biofuel chemical looping applications due to its high availability. In addition content of iron which contributes oxygen-carrying capacity, LD slag contains a significant amount calcium. Calcium, however, is known interact with sulfur, may affect the usability slag. To get better understanding interaction between sulfur and batch scale experiments have performed using solid gaseous fuel or without dioxide, together carrier. The reactivity were compared benchmark ilmenite. Sulfur increases gasification rate char conversion CO both However, no effect could be seen on model tar species benzene. increased was suspected originate from surface-active increasing transfer partly absorbed into particles calcium, forming CaS and/or CaSO4. This, in turn, blocks catalytic CaO towards water gas shift reaction. When SO2 vapor pressure decreased, released SO2. This indicates that loop-seals air reactor continuous process.

متن کاملCFD Analysis of Influence of Slag Viscosity on the Splashing Process in an Oxygen Steelmaking Converter
Physical properties of molten slag such as viscosity, density and surface tension have a significant influence on the slag splashing process in an oxygen steelmaking converter. Particularly, viscosity determines the shear forces that rule droplets formation. Besides, stirring of the molten slag bath strongly depends on this property. In this work, the influence of viscosity on the efficiency of...
