Metals like Fe, Ca, Mn present in sewage sludge ash have been deposited on high surface ?-alumina with high mechanical resistance used as bed materials during sewage sludge fluidized bed combustion to produce low-cost CLC oxygen carriers. The produced oxygen carriers have been characterized using ICP-MS, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and surface area (BET) analysis. H2 Temperature Programmed Reduction (TPR) experiments have been performed to study the redox behaviour of the oxygen carrier and reduction/oxidation cycles have been carried out to assess the carrier stability. The performances of the oxygen carrier in methane combustion/air regeneration cycles in a fluidized bed reactor have been evaluated.

Abstract
Metals like Fe, Ca, Mn present in sewage sludge ash have been deposited on high surface ?-alumina with high mechanical resistance used as bed materials during sewage sludge fluidized bed combustion to produce low-cost CLC oxygen carriers. The produced oxygen carriers have been characterized using ICP-MS, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and surface area (BET) analysis. H2 Temperature Programmed Reduction (TPR) experiments have been performed to study the redox behaviour of the oxygen carrier and reduction/oxidation cycles have been carried out to assess the carrier stability. The performances of the oxygen carrier in methane combustion/air regeneration cycles in a fluidized bed reactor have been evaluated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
