BACKGROUND: Diesel mainly consists of paraffin and thio-aromatic compounds. Sulfur present in diesel exhaust is the major challenge for oil refineries. Sulfur is an oxidizing element that discharges as acute pollutant in the environment which has adverse effects on human and on animal life.
INTRODUCTION: The scope of this review paper is to discuss and to highlight the recent advancements in process of desulfurization of diesel oil to explore the less energy intensive and more economical process.
METHOD: Recently, different techniques are widely used for desulfurization of diesel oil to remove sulfur containing compounds from diesel. These techniques mainly involve hydrodesulfurzation, oxidative desulfurization, biodesulfurization, ionic liquid desulfurization, and adsorption desulfurization.
CONCLUSION: Adsorptive desulfurization technique is green, less energy incentive, and more economical technique than hydro-desulfurization, oxidative desulfurization, ionic liquid desulfurization and bio desulfurization. Optimization of adsorptive desulfurization technique may yield up to 100% desulfurization of diesel oil.
