微波场中甲烷部分氧化制合成气——Ni/ZrO_2催化剂在微波场中的升温行为及催化活性

Partial Oxidation of Methane to Syngas in Microwave Field The temperature rising behavior and reactivity of Ni/ZrO 2 in microwave field

考察了不同Ｎｉ含量的Ｎｉ／ＺｒＯ２催化剂在微波场中的升温行为及１０％Ｎｉ／ＺｒＯ２催化氧化甲烷制合成气的反应活性，并与常规加热条件下的反应活性进行了对比。结果表明，四种Ｎｉ含量的Ｎｉ／ＺｒＯ２催化剂在微波场中均能够升温；在达到相同的ＣＨ４转化率时，微波活化方式下催化剂床层温度比常规加热低得多，且产物中Ｈ２和ＣＯ选择性明显高于后者。

The temperature rising behavior of Ni/ZrO 2 catalysts with different Ni contents and the reactivity of 10% Ni/ZrO 2 catalyst for CH 4 partial oxidation to syngas under microwave irradiation have been studied. The more high temperature can be reached, the more content of Ni there is in Ni/ZrO 2. Compared with a conventional heating mode, the temperature of the catalytic bed is much lower and there is a higher selectivity of CO with microwave irradiation.
