摘要
改性后的活性炭表面形成特殊的吸附中心 ,我们研究二氧化碳在其表面的吸附穿透曲线及压力和解吸时间对吸附性能的影响。经过对 Ca2 + 、Mg2 + 、Cu2 + 改性的活性炭吸附剂的研究 ,我们得出 Cu2 + 改性的果壳基活性炭具有很好的对二氧化碳的吸附可逆行 ,而且可逆吸附量受压力变化的影响在一定压力时十分明显 ,因此是一种优良的 CO2 -
Surface of modified activated carbon make special center of adsorption.We investigate breakthrough curve of carbon dioxide on it and infection of pressure,desorption time.By researching activated carbon modified by Ca 2+ ,Mg 2+ ,Cu 2+ ,We arrive at a conclusion that nutshell based activated carbon modified by Cu 2+ have good adsorptive reversibility for carbon dioxide.Moreover reversible adsorption capacity influenced by pressure is remarkable in a certain range,so it is a good adsorbent for CO 2 PSA.
