| 中文摘要: |
| 以大孔Al2O3为基载体，采用沉积-沉淀法和溶胶-沉积法制备了负载型纳米ZrO2/Al2O3复合载体．用XRD、TEM和比表面与孔径测定等手段对载体进行了表征．结果表明，负载型纳米ZrO2/Al2O3复合载体具有较大的比表面积和适宜的孔径分布，纳米ZrO2在载体上呈单层均匀分布．以CH4-CO2重整制合成气为探针反应，考察了Ni/ZrO2/Al2O3催化剂的活性和选择性． |
| 英文摘要: |
| Nanometer ZrO2/Al2O3 composite supports were prepared by deposition-precipitation and sol-deposition methods, The properties of ZrO2/Al2O3 were characterized by means of XRD and TEM, The results showed that the composite supports have greater specific surface area and proper pore distribution, and found that the nanometer ZrO2 was distributed in uniform on the Al2O3. The Ni/ZrO2/Al2O3 catalysts had a better catalytic activity and selectivity for CO2 reforming of CH4 than Ni/ZrO2 catalyst. |
