Adsorption by porous materials is considered to be a promising approach for desulfurization. Activated carbon/Nickel oxide/ Zinc oxide was prepared and used as adsorbents for removal of Thiophene (T), benzothiophene (BT) and dibenzothiophene (DBT) as sulfur compounds from model diesel oil. The prepared materials were characterized by nitrogen adsorption, X-ray diffraction and Fourier Transform Infrared spectroscopy (FTIR). The amount of compounds removed by the aforementioned adsorption is ranked in the following: DBT > BT > T. Adsorption capacity was governed by chemical interaction and pore volume of the adsorbents.  Our results indicate that the sorbents exhibited an efficient and economical way for removing sulfur compounds due to the low-energy consumption, ambient operational temperature and atmospheric pressure; furthermore, there was a simple regeneration method of the spent adsorbents.
