국문 초록

This study investigates the adsorption and desorption performance of low-concentration, low-volatility C₂–C₃ hydrocarbon mixture on activated carbon as adsorbent in packed-bed system under ambient or pressurized conditions. Experiments were conducted by systematically varying following three parameters such as (1) reactor configuration (Length/Diameter ratio), (2) adsorption conditions via temperatures and pressures (3) desorption condition via energies and space velocity (SV), The reactor configuration had a impact factor on effective adsorption and desorption efficiency, and the optimum L/D ratio is in the range of 4-8 in this study. The low boiling point components, C₂ and C₃, show a sharply decrease in effective adsorption capacity as the adsorbent bed temperature increases. To improve the low effecitve adsorption capacity, it was observed that operating under pressurized condition (below 5 bar) led to approximately a twofold increase in effective adsorption capacity. Desorption energy is related to the amount adsorbed, causing the desorption efficiency to converge. However, as the desorption SV increases, the desorption rate becomes faster, while the desorption efficiency tends to decrease. This study experimentally demonstrates the effectiveness of packed-bed reactor configuration (L/D) and operation conditions including temperatures, times, pressures in handling low-volatility hydrocarbon mixtures.
