In order to obtain the reaction characteristics, CO methanation process is numerically investigated in fluidized bed catalytic reactor over Ni/Al₂O₃ catalyst. The catalysts flow behavior is analyzed, which has significant effect on the activity of catalysts. The influences of operation parameter on CO conversion and CH₄ yield are evaluated. The inventory of catalysts and superficial gas velocity will not influence the output of methane but the reaction rates. Meanwhile, the performance of water-gas shift reaction on CH₄ yield is taken consideration during reactions.

Ni / Al ₂ O ₃催化剂在流化床反应器中通过CO甲烷化生产合成天然气

为了获得反应特性，在流化床催化反应器中以Ni / Al ₂ O _3为催化剂，对CO甲烷化过程进行了数值研究。分析了催化剂的流动行为，这对催化剂的活性有重大影响。评估了操作参数对CO转化率和CH ₄收率的影响。催化剂的存量和表观气体速度将不会影响甲烷的输出，但会影响反应速率。同时，在反应过程中考虑了水煤气变换反应对CH ₄收率的影响。
