Why is there a difference in the specific surface area of the adsorbents?
Thread Content
The specific surface area of imported adsorbents is often over 350. Why can’t domestically produced ones reach this level? Please help explain, thank you.
The criteria for evaluating a molecular sieve are not limited to its specific surface area; its mechanical strength also needs to be taken into account. A molecular sieve with a higher specific surface area indicates it has more effective pores, which in turn suggests that its framework has high strength – this is necessary to achieve such a high specific surface area. The problem with molecular sieves in China lies in the ability to ensure sufficient strength in their frameworks. I’m not sure if it’s correct; please correct me.
