a: The support was reported as an adsorbent of natural origin (perhaps sugarcane bagasse)

b: Not reported whether based on total reactor volume or void volume

c: Not reported (possibly based on void volume)

d: Cone shaped

e: Trickling packed bed

PdT – Productivity based on total reactor volume

Pdv – Productivity based on reactor void volume
