A performance indicator for the screening of adsorbent/desorbent pairs for gas‐phase simulated moving bed applications

In a simulated moving bed, the regeneration is accomplished by introduction of third species, desorbent, which later recovered two downstream separations. As such, choice proper adsorbent/desorbent pair critical to ensure effectiveness SMB process. While this can be done comparing separation region for each system, computational effort required extremely high. By developing parameter that uses readily available literature data, selection process sped up and easily accomplished. work, an performance indicator (SPI) suggested. This involves trade-off between adsorption selectivity in presence capacity most retained ratio less species' enthalpies. The developed metric select suitable adsorbent/pair specific gas through simple calculations.
