Adsorption. What else?
[EN] Chemical Engineering today combines Molecular and Materials Engineerig and Process and Product Engineering (ChE=M2P2). Cyclic adsorptive processes (Simulated Moving Bed –SMB and Pressure Swing Adsorption-PSA) will be discussed for “old” and “new” applications making use of “old” and “new” (MOFs) adsorbent materials. After revisiting my memory as PhD student and the First Brazilian Adsorption meeting I will review the basic concepts involved in adsorption processes and then concentrate in three topics: i) Development of alternative technologies for the “old” propane/propylene separation, based on PSA and SMB with “conventional” and “new” MOF adsorbents; ii) Revisiting an “old” technology – SMB- in what concerns xylenes separation and “new” chiral separations; and iii) Process intensification combining catalytic reversible reactions with selective removal of products by adsorption in Simulated Moving Bed Reactor (SMBR) and Sorption Enhanced Reaction Process (SERP) for hydrogen production by methane steam reforming or ethanol reforming with CO2 capture. Some examples of SMBR from my lab include acetalization (synthesis of green fuel blending agents diethylacetal and dibuthyl acetal) and esterification (ethyl lactate) reactions and xylenes isomerization/separation.
