Abstract Petroleum refinery has been developed for production of transportation fuel with light alkenes and benzene, toluene, ethylbenzene, and xylenes (abbreviated BTEX), but global market demands are shifting to chemicals produced from light alkenes and BTEX. Additionally, the sort of feedstock oil becomes more multifaceted. Fluid catalytic cracking mainly produces gasoline from residual oil over the catalyst matrix including USY zeolite. Addition of ZSM-5 zeolite to the catalyst can increase yield of propylene. The activity and stability are improved by the incorporation of phosphine, alkali earth metal, and transition metal. Hydrocracking principally produces light saturated hydrocarbons over bifunctional catalyst, which are composed of hydrogenation/dehydrogenation catalyst loaded on solid acid. Ultraheavy oil contaminated by sulfur, nitrogen, and metals can be converted into synthetic crude oil by hydrocracking. In addition, the novel process with dealkylation is introduced for the production of chemicals. Dealkylation of alkylpolycyclic aromatic hydrocarbons in crude oil is made solely to proceed, and then the produced alkane keeping the long chain length and polycyclic aromatic hydrocarbon with no alkyl branch are separated by solvent extraction. Alkanes are utilized as diesel fuel and kerosene, whereas polycyclic aromatic hydrocarbon is converted into benzene and its derivatives through partial hydrogenation and ring opening.

炼油厂原油提质催化技术创新

摘要 炼油厂已开发用于生产轻质烯烃和苯、甲苯、乙苯和二甲苯(简称 BTEX)的运输燃料,但全球市场需求正在转向由轻质烯烃和 BTEX 生产的化学品。此外,原料油的种类变得更加多方面。流化催化裂化主要是通过包括 USY 沸石在内的催化剂基质从残油中生产汽油。在催化剂中加入ZSM-5沸石可以提高丙烯收率。通过掺入膦、碱土金属和过渡金属,提高了活性和稳定性。加氢裂化主要是在双功能催化剂上生产轻质饱和烃,其由负载在固体酸上的加氢/脱氢催化剂组成。被硫、氮污染的超重油,金属可以通过加氢裂化转化为合成原油。此外,还引入了用于生产化学品的脱烷基化新工艺。原油中烷基多环芳烃的脱烷基单独进行,然后通过溶剂萃取分离出保持长链长的烷烃和没有烷基支链的多环芳烃。烷烃用作柴油和煤油,而多环芳烃通过部分加氢和开环转化为苯及其衍生物。然后通过溶剂萃取分离生成的长链烷烃和无烷基支链的多环芳烃。烷烃用作柴油和煤油,而多环芳烃通过部分加氢和开环转化为苯及其衍生物。然后通过溶剂萃取分离生成的长链烷烃和无烷基支链的多环芳烃。烷烃用作柴油和煤油,而多环芳烃通过部分加氢和开环转化为苯及其衍生物。
