Sammanfattning

Chemical-looping combustion (CLC) of biomass has the potential to facilitate negative CO ₂ emission in heat and power production when combined with a carbon capture technique. However, typical biomass contains alkali metals and chlorine compounds, such as potassium chloride, which can lead to corrosion of heat-transfer surfaces in the reactors. The combined influence of potassium chloride, hydrochloric acid, and oxygen on the corrosion of five typical heat-transfer materials, which are potential candidates for use in the fuel reactor in a CLC process, was studied using one-week laboratory-scale experiments. The results suggested that potassium chloride, especially in the presence of HCl and O ₂, greatly affects the corrosion of lower-alloyed heat-transfer materials. The outcome of this study can provide valuable information for selecting suitable heat-transfer materials for CLC.
