Supercritical Exsorption (SCEXS), simultaneous supercritical extraction and sorption (adsorption and/or desorption), is a novel process which may have potential for applications in chemical, biochemical and environmental engineering. The system of interest consists of a fixed-bed packed with an adsorbent (e.g., activated carbon or catalyst) through which a so~vent stream (e.g., supercritical carbon dioxide) and a feed stream (e.g., an aqueous stream with low concentration of solute such as phenol) flow countercurrently.
In this work, the theoretical foundations of SCEXS have been established through distributed-parameter modeling which enables phenomenal description of several probable three-phase mass transfer dynamics taking place in the …
