利用高压釜反应装置,在高温高压含水条件下对柴油与硫酸镁热化学还原反应体系进行了模拟实验研究。通过气相色谱仪、微库仑仪、毛细管气相色谱/脉冲火焰光度检测器、红外光谱仪及X射线衍射仪对气、油、固三相产物分别进行了分析,并进行了动力学研究。结果表明,该体系在温度450～550℃内可以发生热化学还原反应,主要生成氧化镁、硫、焦炭、硫化氢、二氧化碳以及硫醇、硫醚和噻吩类等一系列有机硫化物,反应活化能为58.6kJ/mol。

Thermal simulation experiments on the system of diesel and magnesium sulfate were carried out using an autoclave operated at high temperature and high pressure in the presence of water. Properties of the gas-oil-solid 3-phase products were analyzed by some advanced analytical methods including gas chromatography, microcoulometry, capillary gas chromatography combined with a pulsed flame photometric detector (GC-PFPD), FT-IR and X-ray diffraction. The results show that the reaction can proceed at 450~550℃ to produce MgO, S, C, H2S, CO2, and a series of organic sulfur compounds such as mercaptans, sulfoethers and thiophenes as the main products. The reaction kinetics was also studied and the activation energy of the reaction is 58.6 kJ/mol.
