考察了镍基和钴基催化剂催化甲烷在自放热条件下部分氧化制合成气．结果表明，在较高的空速条件下，反应一旦引发即可停止供热，仅靠反应自身放出的热量就能维持反应的继续进行；Ｎｉ／Ｌａ２Ｏ３催化剂中的镍负载量大于１０％后，镍负载量对催化活性无明显的影响；ＣＨ４的转化率及Ｈ２和ＣＯ的选择性均随空速（８４～１８０Ｌ·ｇ－１·ｈ－１）和反应温度的增加而提高；对Ｎｉ／ＺｒＯ２和Ｃｏ／ＺｒＯ２催化剂，反应进行到６～１２ｈ时，ＣＨ４转化率最高；但对Ｎｉ／Ｌａ２Ｏ３和Ｃｏ／Ｌａ２Ｏ３催化剂，随反应的进行，催化活性明显下降．反应过程中活性金属的流失，可能是造成催化活性随时间延长而下降的原因之一．
The partial oxidation of methane to the syngas under self-exothermic conditions was investigated for nickel-based and cobalt-based catalysts. The results show that under the condition of higher airspeed, the reaction can be stopped once the reaction is initiated, and the reaction can be maintained only by the heat released by the reaction itself. When the nickel loading in the Ni / La2O3 catalyst is more than 10% Nickel loading had no significant effect on the catalytic activity. The conversion of CH4 and the selectivity of H2 and CO both increased with the increase of space velocity (84-180 L · g-1 · h-1) and reaction temperature. For Ni / ZrO2 and Co / ZrO2 catalysts, the conversion of CH4 was the highest when the reaction was carried out for 6 ~ 12h, but the catalytic activity decreased obviously with the reaction of Ni / La2O3 and Co / La2O3. The loss of active metals during the reaction may be one of the reasons for the decrease of catalytic activity with time.
