摘要

该研究考虑了一种方法,包括真空瓦斯油的初步氧化、氧化产物的色谱分离以及热处理。报告分析了用过氧化氢和甲酸混合物氧化的真空瓦斯油中极性和非极性成分裂解过程中形成的产物。结果表明,对非极性成分进行热处理,可以获得沸点高达 360 ℃、含硫量小于 0.3 wt% 的馏分油,馏分油的重量比可达 85%。对极性成分进行热处理后,馏出物馏分的含量约为 50%,硫的去除率达到 50%。研究表明,极性氧化产物的裂解温度决定了脱硫的途径:在 450 °C 的温度下,含硫碎片积聚在焦炭中,而在 500 °C 的温度下,它们主要被破坏,形成气体成分。据测定,氧化真空瓦斯油的极性和非极性成分在热处理过程中形成的气体产物主要包括 C1-C3 系列饱和碳氢化合物和二氧化碳。将极性和非极性组分分开裂解的优点是消除了这些组分在热分解过程中形成的产物对系统中进行的反应路线的不良影响。以这种方式获得的产品具有更高质量的特点。此外,通过改变氧化真空瓦斯油中不同成分的裂解条件,可以调节成分破坏的深度,从而调节整个工艺过程的物料平衡。

THERMAL STABILITY OF THE OXIDATION PRODUCTS OF VACUUM GAS OIL
An approach including preliminary oxidation of vacuum gas oil, chromatographic separation of oxidation products, and thermal treatment is considered. Analysis of the products formed in the cracking of polar and non-polar components of vacuum gas oil oxidised with a mixture of hydrogen peroxide and formic acid is described. It has been established that heat treatment of non-polar components allows obtaining up to 85 wt% distillate fractions boiling up to 360 °C, with sulphur content less than 0.3 wt%. The heat treatment of polar components leads to the formation of distillate fractions at a level of about 50 wt%, and sulphur removal reaches 50 %. It has been shown that the cracking temperature of polar oxidation products determines the route of sulphur removal: at a temperature of 450 °C, sulphur-containing fragments are accumulated in coke, while at 500 °C they are predominantly subjected to destruction with the formation of gas components. It has been determined that gaseous products formed in the heat treatment of both polar and non-polar components of oxidised vacuum gas oil mainly consist of saturated hydrocarbons of the C1-C3 series and carbon dioxide. The advantage of separate cracking of polar and non-polar components is elimination of undesired effect on the products formed in thermal decomposition of these components on the route of reactions proceeding in the system. The products obtained in this way are characterized by higher quality. In addition, variation of cracking conditions for separate components of oxidized vacuum gas oil makes it possible to regulate the depth of components destruction and, accordingly, the material balance of the process as a whole.
