Global warming and climate changes are the ultimate consequences of increased CO₂ volume in the air. Physical activation was used to prepare high-throughput activated carbon from a low-cost date stone. The adsorption performance of activated carbon using fixed bed for CO₂ separation was studied. The reliance of temperature, flow rate, and initial CO₂ concentration levels on breakthrough behaviour was analysed. The adsorption response was explored in terms of breakthrough and saturation points, adsorption capacity, temperature profiles, utilization factor, and length of mass-transfer zone. Increased temperatures lead to vary the breakthrough periods notably. The vastly steep breakthrough curves reveal satisfactory utilization of bed capacity. L_MTZ is varied positively with increased feed rates and temperatures. The high utilization factor of 0.9738 with 1.66 mmol/g CO₂ uptake was acquired at 298 K and 0.25 bars. The findings recommend that the carbon prepared from date stone is encouraging to capture CO₂ from CO₂/N₂ mixture.

全球变暖和气候变化是空气中CO ₂量增加的最终结果。物理活化用于从低成本的枣石制备高通量活性炭。研究了固定床对CO ₂分离的活性炭吸附性能。分析了温度，流速和初始CO ₂浓度水平对突破行为的依赖性。从突破点和饱和点，吸附容量，温度分布，利用率和传质区长度等方面探讨了吸附反应。温度升高导致显着改变突破时间。陡峭的突破曲线显示出令人满意的床容量利用率。大号随着进料速度和温度的升高，_MTZ呈正向变化。在298 K和0.25 bar下获得了1.738 mmol / g CO ₂吸收的0.9738的高利用率。研究结果表明，由枣石制得的碳有助于从CO ₂ / N ₂混合物中捕获CO ₂。
