【摘要】 SO₂是油页岩燃烧产生的主要污染气体。对油页岩燃烧过程中SO₂释放机理的研究，有助于高效控制SO₂的释放。应用基础特性实验和燃烧实验研究了北票油页岩燃烧过程中有机硫和无机硫的释放规律。采用酸洗对北票油页岩进行了干酪根提取，应用低温灰化仪进行了矿物质的制备。将制备的样品通过XRD、SDS350、XPS等进行了表征，完成了硫定性和半定量的研究。应用TG-MS（热重-质谱仪）联用，对样品进行了燃烧特性分析，TG研究了燃烧过程中样品随着温度升高而质量损失的过程，MS研究了样品燃烧过程中SO₂随温度升高的释放规律。对SO₂的释放曲线进行分峰拟合，结合XPS,得到硫的不同的赋存形式，系统完整地提供了北票油页岩燃烧过程中硫的释放过程。更多还原

【Abstract】 SO₂ is the main polluting gas produced by oil shale combustion process.The study of SO₂ release mechanism in oil shale combustion process can help to control SO₂ release more efficiently. In this paper, we applied basic characterization experiments and combustion experiments to study the release patterns of organic and inorganic sulfur during the combustion of Beipiao oil shale. The Beipiao oil shale was extracted by acid washing with casein root, and the mineral preparation was carried out by applying low-temperature ashing instrument. The prepared samples were characterized by XRD, SDS350, XPS and other advanced instrumental detection methods, and the qualitative and semi-quantitative study of sulfur was completed. Combined TG-MS（Thermogravimetric-mass spectrometer） was applied to analyze the combustion characteristics of the samples. TG studied the process of mass loss of the samples with increasing temperature during combustion, and MS studied the release pattern of SO₂ with increasing temperature during the combustion of the samples. The release curves of SO₂ were fitted to the split peaks and combined with XPS to obtain different fugitive forms of sulfur, thus providing a systematic and complete picture of the sulfur release process during the combustion of Beipiao oil shale.更多还原
