Abstract
In gasification and combustion processes of biomass, the adsorptive mass transport of relevant gases in the porous structure of particles is of most interest, since diffusion can be a limiting factor to the reaction rate during conversion. Therefore, this study presents an experimental data basis for the kinetic adsorption behavior of H2O vapor as one of the three main components in an oxyfuel atmosphere. Considering the implementation of diffusion and mass transport properties in char conversion modeling, a pore-structure dependent kinetic adsorption (PSK) model was previously developed based on kinetic adsorption measurements. After the successful validation using comprehensive kinetic adsorption data sets of O2 and CO2, this work provides new insights into the distinct adsorption behavior of H2O vapor in order to develop the PSK model even further.
