This study is being performed as part of a graduate thesis project at the University of Northern British Columbia.We are attempting to develop an alternative method for removing sulfur compounds from the fluid catalytically cracked stream of gasoline(FCC gasoline).Canada recently developed new regulations for the amount of total sulfur in fuel,as of January 1~(st) ,2005,thereby limiting the total sulfur to 30 ppmw.This paper reports on our work to date using a Raney-nickel type catalyst for the removal of sulfur-containing compounds from FCC gasoline.We will report on the successful results we have achieved to date including experiments where temperature and reaction time were varied.Raney-type nickel is activated with an alkaline solution,then reacted with the FCC gasoline to form a nickel sulfide precipitate.Our most promising results indicate a 60%drop in total sulfur concentration in the treated FCC gasoline.This reaction occurs at ambient temperatures and pressures and is currently being performed on a laboratory scale.The samples are analyzed using UV Fluorescence Spectroscopy in order to determine total sulfur content.
