Abstract:
A new iron- based promoted catalyst designed to be charged into the industrial radial- axial flow reactor was
investigated in an Accelerated Surface Area and Porosity Analyzer- Micrometrics ASAP 2020. The primary experimental
curve was identified as an adsorption/ desorption isotherm of type IV with H1 hysteresis. The main textural parameters
(surface area, pore volume / porosity, pore size distribution (PSD) and average pore diameter) have been assessed usind six
calculation methods : Langmuir model, BET equation, Single point method, t- Plot method, BJD adsorption, and BJH
desorption. The surface area was between 12.33 m2
/g (Single point method) and 17.48 m2
/g (Langmuir model). From BET
surface area the t- Plot has shown that about 9% was due to micro- pores. The average pore diameter derived from BJH
adsorption model was of 16.72 nm. The determined parameters predict a better activity of the new catalyst compared to the
traditional one.
