The Growth and Evolution of Biomass Soot in Partial Oxidation-Assisted Hot Gas Filtration

At present, partial oxidation is applied in the filtration processes of biomass hot gas to aid solving blockage problems caused by tar and dust condensates. However, resulting high-temperature oxygen-limited environment, risk polymerization forming soot created during purification processes. Thus, this work established a hardware-in-the-loop simulation model using Lagrangian method coupled with chemical reactions on particle surface. The was then used simulate entire evolution process soot, including its formation, growth, interception. results confirmed that under conditions, increase tar’s conversion rate promotes formation soot. Further analysis indicated field formed as result naphthalene/oxygen ratio are main reasons for formation. On other hand, growth inhibited oxidation, which mainly reflected relatively smaller increasing magnitude mass decrease rate. Although cannot be completely avoided, beneficial interception escape can minimized varying premixed oxygen content. basis, potential oxidation-assisted further investigated analyzed.
