摘　　要：介绍了我国独创的Fe1-xO基A30 1型低温低压氨合成催化剂在大型合成氨装置的工业旁路试验 ,考察了原粒度A30 1催化剂在大型合成氨装置实际工况条件下的活性数据。在Kellogg型合成工艺 (15MPa ,10 0 0 0h-1)下出口氨浓度可达 2 1 19% ;在托普索型合成工艺 (18 5MPa ,180 0 0h-1)下出口氨浓度可达 2 0 72 % ,验证了实验室研究结果。工业旁路试验结果表明 :A30 1催化剂可以在我国引进的各类大型合成氨装置中应用。可以提高氨净值 ,降低反应压力和温度 ,减少循环气体流量和放空气量 ,达到节省动力消耗和气体单耗 ,增加合成氨产量的目的。A30The testing of A301 ammonia synthesis catalyst was in a “sidestream” unit,in which the catalyst was present as a packed bed of commercial size material and was subjected to plant conditions of a Large Ammonia Plant.The initial activation of catalyst A301 under plant conditions and the behavior of the catalyst in response to abnormal operation and upset conditions were investigated.The results from the sidestream confirmed the findings from the microreactor of laboratory.A301 is the optimun catalyst that has been demonstrated to work economically and efficiently under the conditions or Large Scale Ammonia Plant.
