Adsorption of Sulfur Compou nds from Liquid Fuel by Carbon Na noparticles Dispers ed in Aqu eous Phase: Kinetic and equilibriumS tudies

Removal of organ osulfur com pounds from liquid hydrocarbo n fuels hav e become a worldwi de increasingly important issue and active res earch subje ct in envir onmental an d energy survey. Sulf ur compounds in fuels have detrim ental effects in environment due to convertin g to sulfur oxides during combustion of transportation fuels, thereby contributin g to air pollution and acid rain [۱]. The primary focus of the new re gulation is the reductio n of sulfur in transportation fuels. The sulfur content mu st drop fro m ۵۰۰ ppm w to less tha n ۱۵ ppmw in diesel and from ۳۰ ۰ ppmw to less than ۳۰ ppmw in ga soline [۲]. In the present work dispersed carbon nanoparticles (CNPs) in aqueou s solution which can be prepared by a clean, cheap and c onvenient rout was u sed for ad sorption of benzothio phene (BT ), dibenzothiophene ( DBT) and dimethyldibenzothioph ene (DMD BT) from organic pha se (heptane). The experiments wer e carried o ut in the bat ch mode form both equilibrium an d kinetic point of view .
