| 摘 要： | 用浸渍法和共浸渍法分别制备了Ni Al2O3和Ni-Ca Al2O3催化剂,在常压连续流动固定床反应器上,研究了氧化钙对Ni Al2O3催化剂萘的转化率、CO、H2和CO2的收率以及它们的选择性的影响,比较了在Ni Al2O3和Ni-Ca Al2O3两种催化剂上萘水蒸气转化所产生的H2 CO比例大小、积炭量和有机副产物的区别。试验发现,氧化钙助剂的加入增强了Ni Al2O3催化剂的活性和抗积炭性能。

| Abstract: | The catalysts of Ni/Al_2O_3 and Ni-Ca/Al_2O_3 were prepared respectively by impregnation and co-impregnation. The effect of CaO incorporation on the conversion of naphthalene, yields and selectivities of H_2,CO, had been investigated. The difference of the ratio of H_2/CO, the carbon deposit and the amount of the organic by-products between the catalysts Ni-Ca/Al_2O_3 and Ni/Al_2O_3 had been compared. It had been confirmed that adding the CaO not only improve the conversion of naphthalene and the yields of H_2, CO, but also increase the selectivities of H_2,CO_2, nevertheless decrease the selectivity of CO. It is also found that the catalyst with CaO can improve the ratio of H_2/CO and decrease the carbon deposit, but do not affect the sort of the by-products and the content of the benzene. |
