摘　　要：研究了Co/γ Al2O3,Co/α Al2O3和Co/SiO2催化剂上的甲烷部分氧化与甲烷二氧化碳重整制合成气反应,只有Co/α Al2O3是有效的.证明Co和载体的相互作用过强或过弱都不利与此耦合反应.Co和α Al2O3的作用正好合适.此外,Co的担载量和催化剂稳定性关系很大,Co量过低则在反应过程中会因Co0→CoAl2O4而失活,Co担载量过高则会导致严重结碳.The combined partial oxidation and CO2 reforming of methane to synthesis gas was investigated on the reduced Co/γAl2O3,Co/αAl2O3 and Co/SiO2 catalysts. Only Co/αAl2O3 has proved to be a efficient catalyst. It is found that the interaction between Co and support too weak or too strong will not be efficient to the combined catalytic partial oxidation and CO2 reforming of methane to synthesis gas. However,its catalytic stability is greatly depends on the Co loading. Low Co loading will lead to phase transfer from Co0 to CoAl2O4 but too high Co loading will result in carbon deposition.
