“Z417/Z418催化剂组合”相比原有催化剂组合优点:
1.几何表面积增加20%以上,对提高转化活性起到了明显的作用;
2.催化剂装填密度减少了5-10%,空隙率提高,有利于气流分布和传热,床层阻力降下降约20-25%,节能降耗效果明显。
3.  成功应用实例:
(1)镇海制氢装置更换为Z417/Z418后,制氢能力从20000Nm3/h扩产到25000Nm3/h。
   (2)齐鲁二制氢装置更换为Z417/Z418后,制氢能力从40000Nm3/h扩产到50000Nm3/h。

The advantages of catalyst combined scheme-Z417/Z418 compared with the original combined scheme.
1.The surface areas has increased by over 20  percent which results a significant increase of the catalytic activity.
2. The loading density of catalyst was reduced by 5 to 10 percent. The improved spacing ratio  is beneficial to the flow distribution and heat transfer. what is more, the bed resistance was reduced by 20 to 25  percent. Finally it has got a remarkable effect on energy-saving and consumption-lowering.
3.The successful example
(1)The hydrogen production of Zheng Hai has  increased from 20000Nm3/h to 25000Nm3/h after the catalyst was replace by Z417/Z418 .
(2)The hydrogen production of Qi Lu  has  increased from 40000Nm3/h to 50000Nm3/h after the catalyst was replace by Z417/Z418 .
Keywords: surface areas catalysts Qi Lu
