Christoph Hahn

If the catalyst is not mixed with the inert gamma alumina than only the volume of the catalystbed is used for the GHSV calculation.

Tellys Lins Almeida Barbosa

For the FT reaction, I will dilute it with inert (alumina), in this case, I consider the sum of Alumina + catalyst for the calculation of GHSV?

Thanks, Christoph

In this case you have to consider the total volume of the resulting catalyst/alumina bed
