| 摘 要： | 在不同条件下采用并流共沉淀法制备了Ni-CaO-ZrO2催化剂,并将其用于CH4的三重整反应过程。以CH4的转化率和催化剂稳定性为指标,研究了催化剂制备过程中各工艺参数对其催化性能的影响。结果表明,催化剂的最佳制备条件为:焙烧温度973 K、前驱体沉淀pH=10~12、回流时间24 h。在该条件下得到的催化剂具有适宜的比表面积和Ni-ZrO2相互作用,在常压、973 K的反应条件下CH4的转化率能够达到70%,具有较高的催化活性和稳定性。

| Abstract: | Ni-CaO-ZrO2 catalysts were prepared by co-precipitation under different conditions and used in the tri-reforming of methane;the influence of preparation conditions on methane conversion and catalytic stability was evaluated.The results indicated that the optimal parameters used to prepare Ni-CaO-ZrO2 catalysts include a calcination temperature of 973 K,a pH value of 10~12 for co-precipitation,and a reflux duration of 24 h.The catalyst prepared under the optimal conditions has a proper surface area and Ni-ZrO2 interaction;it exhibits promising catalytic activity and stability in methane tri-reforming,and the methane conversion exceeds 70% under a temperature of 973 K and atmospheric pressure. |
