采用过渡应答法研究了J105 Ni催化剂上CO的吸附行为以及CO歧化反应与甲烷化反应。实验结果表明,在J105上甲烷化反应机理为直接解离机理,其中CO解离为反应的控制步骤,由此提出了J105 Ni催化剂上可能遵循的甲烷化反应机理。
The transitional reaction method was used to study the CO adsorption behavior and the CO disproportionation reaction and methanation reaction on the J105 Ni catalyst. The experimental results show that the mechanism of methanation on J105 is direct dissociation mechanism, in which CO dissociation is the control step of the reaction, and the possible mechanism of methanation on J105 Ni catalyst is proposed.
