摘要: 采用化学氧化法对高硫石油焦的脱硫规律进行研究。以双氧水为氧化剂,甲酸、乙酸和丙酸为催化剂,考察了石油焦粒度、氧化剂体积与石油焦质量之比(液固比)、反应时间和反应温度等因素对脱硫效果的影响。结果表明,双氧水⁃甲酸氧化体系的脱硫效果最好,明显优于其他两种氧化体系,在石油焦粒度为100目、液固比为20 mL/g、氧化反应时间为18 h、反应温度为60 ℃的最佳工艺条件下,石油焦的硫质量分数由3.32%降至2.65%,脱硫率达到20.2%。

Abstract: The desulfurization law of high sulfur petroleum coke was studied by chemical oxidation method. In this paper, hydrogen peroxide was used as oxidant, formic acid, acetic acid and propionic acid were used as catalysts. The influences of petroleum coke particle size, the ratio of oxidant volume and petroleum coke mass (liquid⁃solid ratio), reaction time and reaction temperature on the desulfurization effect were investigated. The experimental results show that the desulfurization effect of hydrogen peroxide⁃formic acid oxidation system is the best, which is better than the other two oxidation systems. The petroleum coke particle size is 100 mesh, the liquid⁃solid ratio is 20 mL/g, the oxidation reaction time is 18 hours, and the reaction temperature is 60 ℃ for oxidation. Under the optimum conditions of the desulfurization experiment, the sulfur content of petroleum coke decreased from 3.32% to 2.65%, and the desulfurization rate reached 20.2%.

Key words: Petroleum coke, Desulfurization, Chemical oxidation
