摘要：In this study, performance evaluation of activated
carbon in a continuous packed bed column for the removal of
dibenzothiophene (DBT) from petroleum distillates is reported.
Model diesel containing only DBT was desulfurized by
adsorption using activated carbon as an adsorbent in
continuous mode. Scanning electron microscope (SEM)
equipped with energy dispersive X-ray (EDX) was used to
check the morphology and elemental compositions of the
adsorbent. Surface chemical functionalities were checked using
Fourier transform infra-red (FTIR) spectroscopy. The results
show that about 16 mg kg-1
adsorption capacity of the
adsorbent for adsorbate at 3 ml min-1
and adsorbent amount of
2.0 g. In addition, the adsorption the adsorption behavior of
the adsorbent could be perfectly described with Langmuir
isotherm model. The kinetics of the adsorption could be
described well using Bohart Adams and Thomas models.
