| 摘 要： | 以不同浓度硝酸处理的活性碳(AC)为载体,制备了Co-Zr-La/AC催化剂,并考察了其催化CO加氢制备高碳醇(C6以上)的反应性能.通过Boehm滴定法和N2物理吸附考察了各AC的表面性质,并采用CO化学吸附、程序升温还原和X射线衍射对催化剂进行了表征.结果表明,经硝酸处理后,AC表面酸性基团(如羧基和内酯基)的数量...

| Abstract: | Activated carbon(AC) was treated with nitric acid of different concentrations prior to the preparation of Co-Zr-La/AC higher alcohol synthesis catalysts. The effect of acid pretreatment on the catalyst activity was studied. The surface properties of the samples were investigated by Boehm titration and N2 physisorption. And the Co dispersion,reduction properties,and physical structure of the catalysts were characterized by CO chemisorption,temperature-programmed reduction,and X-ray diffraction(XRD) ,respecti... |
