IUPAC recommendations, as well as providing tricks for overcoming common
problems during gas adsorption experiments.
The third chapter provides a brief description of the state of the art of molecular
simulations applied to zeolites, as well as a discussion of current challenges in the
field. Today, experimental and computational studies must be closely linked to gain
a deep understanding of adsorption and diffusion of molecules through the zeolite
channel systems needed for the optimization of the adsorption and separation
processes.
The fourth chapter is a compendium of the above approaches. There, it is shown
how the rational selection of adsorbents, by taking into account their chemical and
structural properties is possible to achieve high separation performances in industrially and environmentally relevant processes for the recovery of bio-alcohols coming
from renewable resources.
Chapter “Measurement of Diffusion in Small Pore Zeolites to Improve Selectivity
in Separation Processes” focuses on the experimental determination of adsorption
kinetics in zeolites. The determination of diffusional parameters is a keystone in the
design of the separation processes. In this chapter, the zero-length column (ZLC)
technique has been extensively discussed for understanding the kinetics of CO 2
adsorption in zeolite Rho.
The basis for bridging the gap between academia and industrial application is
discussed in the sixth chapter of this volume. The authors show the main methods
adopted in scaling-up adsorptive gas-phase separations using zeolites, including the
above strategies and process simulation and optimization.
Finally, the last chapter describes the main industrial applications based on
zeolitic adsorbents. Also, this chapter provides insights into how zeolitic adsorbents
should evolve for adapting to new adsorption technologies to result in more efficient
processes.
We hope that this volume on “New Developments in Adsorption/Separation of
Small Molecules by Zeolites” will be of interest for researchers arriving to this field
as well as those that are skilled in the area but could find “inspiration” in what is
described here.
