Abstract

Finding a suitable oxygen carrier that is both cost-effective and highly reactive across multiple cycles in chemical looping processes remains a challenge. Consequently, this research focuses on the assessment of Fe-, Mn-, and Ni-based ores and mine residues as low-cost and sustainable oxygen carriers. Chemical composition, crushing strength, and attrition rate were determined. Their reactivity was evaluated in a thermobalance with CH₄, H₂, and CO, followed by assessment in a batch fluidized bed reactor with the same gases. All materials exhibited good mechanical properties at the outset, except MinMnT, which lacked the required mechanical strength and was subjected to thermal treatment. MinFeC, MinFeF, and MinMnT1000 demonstrated effective oxygen transport capacity and high reactivity both in thermobalance and FBR, with no agglomeration and a lifetime ranging between 3000 and 10,500 h. Given the outstanding performance of MinMnT1000 with CO and H₂, it is considered an excellent candidate for further evaluation in iG-CLC with biomass.

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
