“For the adsorption tests on APTES20, seven concentrations (5%, 8%, 10%, 12%, 15%, 18%, 20%) for both velocities were explored.
In Figure 9 and Figure 10, two breakthrough curves and corresponding temperatures are compared for the velocity 5.6 cm/s in which sorbent was in fixed bed in conventional fluidization or moderately expanded in confined fluidization. The same comparison is reported in Figure 11 and Figure 12 for the velocity 8.6 cm/s that was sufficient to determine the bubbling regime in the conventional fluidization in contrast with the extended homogeneous expansion of the sorbent in the confined bed.”
