摘要：Chemical desulphurization and microwave-chemical desulphurization was employed to remove sulfur in crude oil. Several desulfurizing agents have been selected and investigated. Among these desulfurizing agents, DCP, BPO, BBPV, and BPMC are organic peroxides, while the active oxygen content of organic peroxides is increasing, the oxidation effects become better and the desulfurizing efficiency of crude oil is increasing. BBPV and BPMC are compared with other organic desulfurizing agents, which perform better. Various influencing factors such as dosage of desulfurizer, investigated temperature, and optimum reacting conditions were obtained. The optimized dosage of BBPV, BPMC, and formylhydroperoxide is 1%, 2%, and 15%, respectively. The optimized temperature should be 80-90 degrees C. Microwave inducement can improve the effect of chemical desulphurization and better desulfurizing results were gained. The desulfurizing efficiencies of peroxy acetic acid, BBPV, and BPMC increased from 18.6%, 21.8%, 28.5%, and 24.3% to 34.7%, 33.3%, 34.5%, and 43.3%, respectively. The microwave inducement can decompose sulfone to water-soluble sulfate and sulfite. Thus, organic sulfur was transformed into inorganic sulfur and then removed.
