“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 |
