What is the porosity of activated carbon?
Thread Content
The Chemical Engineering Handbook states 0.33–0.45, but some sources give 0.5–0.75. Which one is correct? Activated carbon is a porous material, so its porosity should be very high.
The Chemical Engineering Handbook states a range of 0.33 to 0.45; this value is presumably calculated based on densely packed spherical particles
No, it also gives the other adsorbents a low porosity.
It’s porosity, not void ratio.
Hello. What was the final porosity value of the activated carbon?
