“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。

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.

Some advantages for “Z417/Z418 combined catalysts” when compared with previous are as follows:
1.        There is 20% increase for specific surface area and it exhibits obvious effect for improving transforming activity;
2.        There is 5%-10% decrease for catalyst’s loading density and the higher porosity  is  favour of gas distributing and heat transfering,the bed resistance decrease around 20-25% and it shows a significant effect for energy saving.
