| 摘 要： | 以介孔SBA-15为结构助剂, 制备出用于甲醇水蒸气重整制氢的新型高效氧化硅掺杂的Cu/ZnO/Al2O3催化剂, 并与传统Cu/ZnO/Al2O3催化剂在相同条件下的催化性能进行了比较. 结果表明, 添加适量介孔SBA-15可显著提高催化剂的催化活性和选择性, 在大幅度提高甲醇转化率的同时有效降低了重整产气中CO的含量. 原位XRD分析证实适量介孔SBA-15的添加对传统Cu/ZnO/Al2O3催化剂的微结构性质可产生重要的调控作用, 从而大大改善其催化活性和制氢选择性.

| Abstract: | Siliceous mesoporous SBA-15 has been proposed as a new effective structural promoter to pre- pare highly effective SiO2-modified Cu/ZnO/Al2O3 catalysts for hydrogen production. It was demonstrated that the SBA-15 modified catalyst exhibited superior performance in terms of methanol conversion and sup- pressed formation of CO during steam reforming of methanol. It was suggested that the intrinsic nature of SBA-15 should favor the generation of modified catalyst with much larger metallic copper surface area and improve copper dispersion. In addition, it was shown by in situ XRD that a considerable increase of the mi- crostrain of Cu nanocrystals could be achieved in the catalysts modified by SBA-15, which correlates well with the enhanced CH3OH conversion as observed on the corresponding samples. |
