In this paper, we present a numerical study of the effect of the bulk sorbent particle packing on the break-through time. In our experiments, we fix the physical and chemical properties of the sorbent particles but vary the packing density (macroporosity) and the CO₂ volume fraction at the inlet. After that, the gas flow through the reactor is simulated, and CO₂ volume fraction as a function of time at the outlet is measured. We show that, in the case of high macroporosity, the recorded CO₂ concentration strongly depends on the macroporosity. On the contrary, if the macroporosity is low, we observe almost no difference in the break-through curves for the models with macroporosity less than 45%.
