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.
