| 1 | 炼油结构转型下沸腾床加氢技术显示文摘STRONG技术是中国石油化工股份有限公司自主开发的沸腾床加氢技术,其创造性提出了气-液-固自分离的三相分离器替代高温高压沸腾泵,实现了气-液-固高效分离和自持流化;创制的适宜不同反应分区的球形催化剂,具有良好流化性能和较高的杂质脱除率,实现了劣质渣油的高效提质和产物分布的灵活调变,而且适应不同原料加工场景(如渣油、煤焦油等)和目标产物(如清洁油品、化工原料、低硫船用燃料油和低硫石油焦等)。目前已建成50 kt/a示范装置和500 kt/a工业装置,并完成百万吨规模的工艺包编制工作。为应对炼油结构转型,在STRONG沸腾床加氢技术基础上,开发出沸腾床-固定床复合床(SiRUT)技术。该新技术具有原料适应性强、装置运行周期长和加氢重油性质显著提升等优点,在现有及未来炼油企业提质增效方面具有竞争优势。 | 仝玉军 杨涛 方向晨 侯栓弟 | 2021 | 石油炼制与化工2021，52，10： | 11 |
| 2 | Reaction Process of Heavy Hydrocarbons Hydrogenation in Ebullated Bed显示文摘The properties and structural changes of unconverted oil(UCO)obtained from ebullated bed hydrogenation at different residue conversion rates were analyzed to clarify the reaction process of heavy components.Meanwhile,the processing routes of UCO,delayed coking,and solvent deasphalting,were investigated.The results showed that with the increase of conversion,the impurity removal rate increased;meanwhile the contents of sulfur and metal in UCO decreased,while the contents of nitrogen and residual carbon increased,and the colloidal stability of UCO became worse.The structural parameters of UCO indicated that the change in molecular structure of heavy oil mainly covered the opening of cycloalkanes ring,hydrogenation saturation of aromatic rings and dealkylation reaction during hydrogenation in the ebullated bed;the aromatic structure was basically unchanged at high conversion,and was mainly due to the ring opening of cycloalkanes and the fracture reaction of alkyl side chains.The coking route of UCO showed that low sulfur petroleum coke with different grades could be prepared by adjusting the conversion in ebullated bed to produce UCOs with different properties.The coke generating coefficient and sulfur transfer coefficient in UCO coking process were higher than those in residue coking.The properties of deasphalted oil(DAO)of UCO were significantly improved and could be used as FCC or hydrocracking feedstock.The DAO yield of UCO feedstock at high conversion was higher,and its sulfur content was lower and CCR value was higher. | Wang Jianjun Tong Yujun Yang Tao Ge Hailong Meng Zhaohui | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，4： | 2 |
