Sulfur-containing compounds are the most abundant compounds in crude oil. Sulfur in liquid fuel oil leads to the emission of sulfur oxides and sulfate particulate matter which not only endangers health and community property but also reduces the life of the catalysts and engines due to corrosion. Various methods, with a high level of precision and sensitivity, have been developed to analyze sulfur-containing compounds. On the other side, the removal and characterization of sulfur-containing compounds in crude oils and petroleum products is of great importance, not only for the downstream refining process, control/optimization, and environmental compliance, but also for upstream geochemical studies for exploration and production. This review summarizes the analytical strategies and some of the most important and promising technologies for the removal of sulfur from oil.

含硫化合物是原油中含量最丰富的化合物。液体燃料油中的硫会导致排放硫氧化物和硫酸盐颗粒物，这不仅危害健康和社区财产，而且由于腐蚀而缩短了催化剂和发动机的寿命。为了分析含硫化合物，已开发出各种方法，具有很高的精确度和灵敏度。另一方面，原油和石油产品中含硫化合物的去除和表征非常重要，不仅对于下游精炼过程，控制/优化和环境合规性，而且对于上游地球化学研究的勘探和开发都非常重要。生产。
