以ＣＨ４ＣＯ２Ｏ２反应为探针，对从天然气水蒸气转化工业装置上卸下的失活ＣＮ１６催化剂进行了再生研究．结果表明，当失活ＣＮ１６催化剂先经氢气还原，再在不同温度下通入再生剂，然后升温至９００℃时，起始再生温度对催化剂的活性影响很小；而当失活ＣＮ１６催化剂不经氢气还原，在不同温度下通入再生剂，然后升温至９００℃时，随起始再生温度的升高，再生催化剂的活性增大．ＸＲＤ和分散度测试结果表明，失活催化剂表面大部分是ＮｉＯ，８００℃以下直接通入再生剂很难使其分散；而将ＮｉＯ先还原为单质Ｎｉ，然后通入再生剂，可以使Ｎｉ重新分散，镍的分散度、比表面积和再生效果能够接近新鲜ＣＮ１６催化剂的水平．失活催化剂经氢气还原，９００℃下通入再生剂，再生后的催化剂在ｎ（ＣＨ４）∶ｎ（ＣＯ２）∶ｎ（Ｏ２）＝１∶０４∶０５，温度为６００℃，空速为８００００ｈ－１的条件下运行１４０ｈ，产物合成气的摩尔分数始终保持在８１％左右，再生催化剂具有良好的活性、选择性、抗积炭性和稳定性．
In order to CH4 CO2 reaction as a probe, from the natural gas water vapor from the industrial unit on the removal of the deactivated CN 16 catalyst was studied. The results show that when the inactivation of CN 16 catalyst first hydrogen reduction, and then pass into the regeneration agent at different temperatures, and then heated to 900 ℃, the initial regeneration temperature of the catalyst activity is very small; and when inactivated CN 16 catalyst without hydrogen reduction, at different temperatures through the regeneration agent, and then heated to 900 ℃, with the initial regeneration temperature increases, the activity of the regenerated catalyst increases. XRD and dispersion test results show that most of the surface of the deactivated catalyst is NiO, it is very difficult to disperse NiO directly through regeneration agent below 800 ℃, while NiO is reduced to elemental Ni first, Dispersion, dispersion of nickel, specific surface area and regeneration effect can be close to the level of fresh CN 16 catalyst. The deactivated catalyst is reduced by hydrogen and introduced into the regenerant at 900 ° C. The regenerated catalyst has the following conditions: n (CH 4): n (CO 2): n (O 2) = 1: 0. 4: Under the condition of airspeed of 80000h-1, the mole fraction of syngas remained at about 81% at all times. The regenerated catalyst had good activity, selectivity, anti-charring property and stability.
