Evidence of the dominant role of particle size in controlling the dynamic adsorption breakthrough behavior of gaseous benzene in a microporous carbon bed system

To learn more about the competing roles of the key process variables (e.g., particle size vs. space velocity) in the adsorption of volatile organic compounds (VOCs), the breakthrough (BT) behavior of gaseous benzene (at 3 Pa) was investigated using microporous activated carbon (AC) beds built individually with each of four different particle size ranges (<0.6, 0.6–1.7, 1.7–2.36, and 2.36–5 mm) at three flow rates (300, 500, and 1000 mL min−1)....
