Abstract
Today, sulfur removal from fuels has improved by new adsorbents such as zeolites
that needs extensive studies. This study investigates the feasibility of sulfur compounds adsorption
on improved nano zeolite existing in organic fuels and desorption of them from nano-adsorbent.
Some properties of improved nano zeolite were analyzed to receive better sulfur compounds adsorption.
Zeolite surface structure was analyzed by TEM (tunneling electron microscopy). Batch experiments
were chosen for adsorption/desorption study of sulfur compounds and adsorption and desorption
conditions were optimized by BBD methodology. The influence of variables in the process, consists
of adsorbent metal percent (0.05-10 wt%), adsorbent calcination temperature (200-500 °C) and
adsorption process temperature (30-120 °C) in adsorption stage and gas flow rate (1.5-3.5 mL/Min),
regeneration temperature (150-300 °C) and desorption time (30-90 Min) which were investigated
using experimental design procedure.
