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, having adverse effects on human and animal life.

Introduction: The scope of this review paper is to discuss and highlight the recent advancements in the process of desulfurization of diesel oil to explore the less energy-intensive and more economical process.

Methods: 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 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.

背景：柴油主要由石蜡和硫代芳香族化合物组成。柴油机尾气中的硫是炼油厂面临的主要挑战。硫是一种氧化元素，作为急性污染物排放到环境中，对人类和动物的生命产生不利影响。

简介：本综述论文的范围是讨论和突出柴油脱硫工艺的最新进展，以探索能耗更低、更经济的工艺。

方法：最近，不同的技术被广泛用于柴油脱硫，以去除柴油中的含硫化合物。这些技术主要涉及加氢脱硫、氧化脱硫、生物脱硫、离子液体脱硫和吸附脱硫。

结论：吸附脱硫技术与加氢脱硫、氧化脱硫、离子液体脱硫和生物脱硫相比，绿色环保，能源激励少，更经济。吸附脱硫技术的优化可使柴油脱硫率达到100%。
