Question

How to calculate surface area of of porous catalyst by using pressure and volume data?

Answer 1

The surface area is usually calculated from BET method (SBET) and the average pore diameter can be estimated by 4VT/SBETratio (VT Total volume and SBET surface area). Also, the mesopore volume can be obtained by difference between total pore volume and micropore volume.
