The rising levels of pollutants has provoked the search for advanced technologies to minimize their effect on environments. The continuous adsorption column is applied to study CO 2  adsorption using two types of adsorbents. The commercial activated carbon Norit-RB2 and developed activated carbon from economic date stone are utilized for the adsorption study. The morphological and surface characteristics have been examined by BET analyzer and scanning electron microscope. The effect of flow rate, temperature, and initial adsorbate volume on breakthrough performance has been investigated. The effectiveness of the CO 2  capture was examined in terms of adsorbate capacity, column efficiency, usable bed length, L MTZ , and utilization factor. The very steep adsorption profiles specify acceptable adsorbent uptake utilization under a breakthrough state. The CO 2  loading of 1.66 mmol/g was reached with a column efficiency of 94.9% for biomass-derived adsorbent at 298 K temperature. The lower CO 2  loading of 0.99 mmol/g and column efficiency of 92.8% have been determined for commercial activated carbon. The reduced L MTZ  equal 1.29 cm and enhanced f equals to 0.974 at 298 K and C o  = 5% are observed for the biomass-derived adsorbent. The findings acclaim that activated carbon derived from date pits is decidedly promising to capture CO 2  by adsorption.
