Economic evaluation of Cu-impregnated manganese for CO2 capture in combustion with solid oxygen carriers

Introduction: Chemical Looping Combustion (CLC) is a promising technology for CO2 capture.Objective: this study aimed to evaluate Cu-impregnated manganese ore (OXMN009P) as an effective oxygen carrier for this process, specifically using CO and H2 as fuels.Methodology: the methodology involved thermogravimetric analysis (TGA) and batch fluidized bed reactor (bFB) testing to assess the material’s performance.Results: he results showed that OXMN009P exhibited a reaction rate index (RI) ranging from 6.1 to 20.1% /min. It also achieved high fuel conversion efficiencies, nearly 100% for H2 and approximately 70% for CO, demonstrating improved reactivity and oxygen transport capacity. Furthermore, the particle lifetime was extended to 2031 hours, significantly reducing the need for annual solids inventory replenishments.Conclusions: in conclusion, the economic analysis suggests that the material cost of OXMN009P would not be a limiting factor for the implementation of CLC technology.
