摘　　要：在固定床反应器中,研究了不同氢碳比、水蒸气加入量以及压力条件下,工业合成甲烷催化剂Ni-MgOAl2O3的积碳情况,结果表明:在以模拟焦炉气(氢碳比5.0)为原料气,压力2.0 MPa,水蒸气加入量10%的工艺条件下镍基催化剂性能更稳定。The effects of process conditions such as hydrogen carbon ratio,reaction pressure and the amount of water vapor on carbon deposition during the process for synthesizing Ni-MgO-Al2O3 were investigated in the fixed bed reactor with practical condition.Experimental results showed that the performance of nickel-based catalyst is more stable under conditions of simulate coke oven gas（ratio of hydrogen to carbon is 5.0） as raw material,the amount of water vapor of 10％ and reaction pressure of 2.0 MPa.
