This study aims to investigate the adsorption-desorption of CO on a micro-mesoporous zeolite-Y-templated carbon (ZTC) at various temperatures. ZTC was synthesized sucrose impregnation, carbonization, and template removal. The adsorption-desorption of CO on ZTC was performed using the gravimetric method. Results showed that the CO adsorption capacity was 9.51 wt%, 5.60 wt%, and 3.47 wt%, and desorbed up to 59.83%, 69.70%, 77.5% for temperatures of 30 °C, 40 °C, and 50 °C, respectively. The adsorption process of CO at temperatures of 30 °C and 40 °C follow the pseudo-second order, while at 50 °C follows intra-particle diffusion. The thermodynamic analyses indicate that the adsorption was due to physisorption.
本研究旨在考察不同温度下一氧化碳在微孔-介孔Y型沸石模板碳（ZTC）上的吸附-脱附情况。ZTC通过蔗糖浸渍、碳化和模板去除合成。采用重量法进行一氧化碳在ZTC上的吸附-脱附实验。结果表明，在30℃、40℃和50℃时，一氧化碳的吸附容量分别为9.51 wt%、5.60 wt%和3.47 wt%，脱附率分别高达59.83%、69.70%和77.5%。30℃和40℃时一氧化碳的吸附过程符合准二级动力学，而50℃时符合颗粒内扩散。热力学分析表明，该吸附为物理吸附。
