NaY ZEOLITES IMPREGNATED WITH NICKEL FOR ADSORPTION OF SULFUR COMPOUNDS FROM FUEL MODEL MIXTURE

Abstract

This work aims to develop new adsorbents for the removal of sulfur from fuels to meet the new regulations for vehicle emissions. A study has been carried out to remove sulfur from the propanethiol/cyclohexene model mixture, at ambient conditions, using Ni/NaY as adsorbent. The material was characterized by EAA, DRX, BET, and TGA. Propanethiol adsorption in cyclohexene was assessed by kinetics in a finite bath system, which was compared with the commercial adsorbent Selexsorb. The sulfur content was analyzed by gas chromatography. Results showed the incorporation of nickel in the structure of Y zeolite with retention of crystallinity and a higher adsorption capacity for Ni/NaY.
