| 英文摘要 | an in-situ modified sol-gel method for the preparation of a ni-based monolith-supported catalyst is reported. with the presence of a proper amount of plasticizer and binder, and at an optimized ph value, the stable boehmite sol was modified with metal ions (ni, li, la) successfully without distinct growth of the particle size. monolith-supported ni-based/gamma-al2o3 catalysts were obtained using the modified sol as the coating medium with several cycles of dip-coating and calcination. combined bet, sem-eds, xrd and h-2-tpr investigations demonstrated that the derived monolith catalysts had a high specific surface area, a relatively homogeneous surface composition, and a high extent of interaction between the active component and the support. these catalysts showed relatively stable catalytic activities for partial oxidation of methane (pom) to syngas under atmospheric pressure. the monolith catalysts prepared by this sol-gel method also demonstrated an improved resistance to sintering and loss of the active component during the reaction process. |
