This hypothesis is verified by comparing the slurry arrangement to a solid working anode where mass transport is not required. In order to maximize the carbon utilization efficiency, operating below the thermodynamic temperature limit for reverse Boudouard gasification (700 °C) is recommended with agitation in slurry-based systems. For a maximum power output, operating under CO₂ at higher temperatures (>800 °C) and passing the CO containing flue gas over an oxygen reduction cathode achieve optimal results.]]> Mon 28 Nov 2022 13:29:36 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46145 Eucalyptus pilularis biomass and ternary molten carbonate eutectic [Li₂CO₃, 43.5%; Na₂CO₃, 31.5%; and K₂CO₃, 25% (mole percentage)] in thermogravimetric analysis at three different temperatures, 600, 750, and 900 °C, was studied. These salts affect the slow pyrolysis process, including changes in the volatile release mechanism and the morphology of remnant char material. The initial results show that, in the presence of molten carbonate, biomass particles make bubble-shaped larger particles, which result in less volatile emissions and more char residue. It is suggested that the ternary eutectic has a chemical diluent and catalytic role, particularly in the case of higher salt doping. Results from scanning electron microscopy images give strong evidence that molten carbonates capture volatiles inside swelling carbon particles, which causes the generation of various sizes of pores as well as char-making reactions, and at a higher temperature, the bubble-shaped particles will rupture. Swelling of this nature has previously only been observed clearly in coal precursors; however, this is the first observation in a biomass-based system. Also, at a temperature above 750 °C, decomposition of molten carbonate generates CO₂ and carbon/carbonate gasification produces CO as well as a more “activated” biochar.]]> Fri 11 Nov 2022 18:31:02 AEDT ]]>
