用热重（ＴＧＡ）方法，研究了ＬａＮｉＡｌ１１Ｏ１９和ＳｒＮｉＡｌ１１Ｏ１９催化剂上甲烷与二氧化碳重整反应的积炭动力学．实验结果表明，甲烷裂解是ＣＨ４＋ＣＯ２反应中主要的积炭反应；甲烷与二氧化碳重整反应的积炭速率随反应温度升高而增大，但其衰减速度也较快；ＣＨ４＋ＣＯ２反应的积炭速率相对甲烷分压的反应级数是１，相对二氧化碳分压的反应级数是－０．５；在ＳｒＮｉＡｌ１１Ｏ１９中掺入Ｌａ３＋离子，提高了催化剂上甲烷裂解反应的活化能，降低了ＣＯ２消炭反应的活化能，从而提高了催化剂的抗积炭能力．
The thermogravimetric (TGA) method was used to study the coke formation kinetics of methane and carbon dioxide reforming reaction on LaNiAl11O19 and SrNiAl11O19 catalysts. The experimental results show that methane cracking is the main carbon deposition reaction in CH4 + CO2 reaction. The carbon deposition rate of methane and carbon dioxide reforming reaction increases with the increase of reaction temperature, but the decay rate is also faster. The carbon deposition rate of CH4 + CO2 reaction is relatively The reaction order of partial pressure of methane is 1 and the reaction order relative to partial pressure of carbon dioxide is -0.5. Incorporation of La3 + ions into SrNiAl11O19 improves the activation energy of methane cracking reaction on catalyst and reduces the activation of carbon elimination reaction Can, thus improving the anti-carbon catalyst capacity.
