Abstract
Ordered mesoporous carbon (OMC) adsorbents
have been prepared using spherical SBA-16 mesoporous
silica, as a template. The synthesized materials were
studied by X-ray diffraction, scanning electron microscopy
and nitrogen adsorption–desorption isotherms. OMCs have
been tested for adsorption of dibenzothiophene (DBT) as
model sulfur compound from gasoline fuels. The OMC
showed higher sulfur adsorption due to large mesopore
volume and high specific surface area. The results confirm
the significance of the adsorbent pore size and its surface
chemistry for the adsorption of DBT from petroleum fuels.
Langmuir and Freundlich isotherm models were used to fit
equilibrium data for OMC. The equilibrium results were
best demonstrated by the Langmuir isotherm.
