摘要
以苯胺和苯为模型,考察了其在载体活性炭(AC)和炭基金属吸附-催化剂(CuO/AC)上的吸附行为,并对吸附了苯胺和苯的AC和CuO/AC进行程序升温脱附实验(TPD).结果表明,CuO/AC的苯胺脱附量显著小于AC,且起始脱附温度高于AC的脱附温度.CuO的担载改变了苯胺的吸附状态,使得苯胺和CuO/AC之间的吸附更加牢固;CuO担载前后的苯的脱附行为差别不大,表明其吸附状态没有变化.
In this paper, the adsorption and temperature-programmed desorption behaviors of aniline and benzene (as model compounds) on activated carbon (AC) and a copper oxide doped activated carbon (CuO/AC) were investigated. Results show that aniline desorption amount from CuO/AC is significantly lower than that from AC, and initial desorption temperature of aniline from CuO/AC is higher than that from AC. CuO addition changes adsorption state of aniline, which can make adsorption interaction between aniline and catalysts be stronger. CuO has no significant effect on desorption behavior of benzene, which shows state of benzene does not change.
