Dual roles of sludge ash in ilmenite reactivity during fluidized bed chemical looping combustion

Key Points

• Ilmenite reactivity significantly increases when sludge ash is present, facilitating better combustion outcomes.
• The presence of sludge ash resulted in a noted 20% improvement in combustion efficiency compared to standard ilmenite.
• Fluidized bed chemical looping combustion was used to assess the reaction dynamics involving sludge ash and ilmenite in this study.
• Understanding these interactions may enable more efficient energy production utilizing waste materials.
