Abstract

This work was conducted to study the effect of selective adsorption on removal of sulfur  compounds  from  Iraqi  heavy  naphtha  from  Al-Dura refinery  by using  molecular  sieve (13X)  in a fixed-bed column and  it was be run out at 1.5–6.0h-1 LHSV, 15–30 gr  weight of molecular sieve (13X), 600–1650ppm sulfur concentration in the feedstock ,  the adsorption  temperature  was  25oC and 40oC.  The best operating conditions for removing sulfur compounds was 3.0 h-1 LHSV, 20 gr molecular sieve bed weight and 25oC temperature, where the sulfur content in heavy naphtha was reduced from nearly 600 ppm to less than 1 ppm (by weight). Regeneration steps was thermally took place by hot air flow in a range from 16.66 – 25 liter / min and temperature range from 200–350oC, the best desorption conditions for (85.8%) weight percent removing was at 16.66 liter / min air flow and 350 oC.
