摘要： 柴油超深度脱硫是生产清洁柴油的关键技术之一。中国石油大庆化工研究中心与中国石油大学（北京）联合攻关,从研究柴油馏分加氢脱硫反应机理和分析柴油超深度加氢脱硫的技术难点入手,采用含有Ti、Si、P元素,并具有规整结构的钛硅和磷铝两种催化材料对氧化铝载体进行改性,利用两种催化材料的协同催化作用,在进行超深度脱硫的过程中实现对氮化物和芳烃的有效脱除,成功开发出PHF超低硫柴油加氢精制催化剂。PHF催化剂具有原料适应性好、脱硫活性高、活性稳定的特点,先后在中国石油10套柴油加氢精制装置上进行工业应用,装置加工能力合计1700×104t/a,完全满足装置生产硫含量小于50μg/g或10μg/g清洁柴油的生产需要。

Abstract: In-depth desulfurization of diesel is one of the key technologies for production of clean diesel. Daqing Chemical Research Center and China University of Petroleum (Beijing) made a joint research on hydrodesulfurization reaction mechanism of diesel fraction and analyzed the technological bottlenecks for in-depth hydrodesulfurization of diesel. With adoption of Ti, Si and P elements, the two catalytic materials of titanium silicon and phosphorus aluminum are used to modify alumina carrier. Based on the coordinated catalysis of two catalytic materials, nitrogen and aromatics are effectively moved in the in-depth desulfurization process. As a result, the PHF ultra-low sulfur diesel hydrofining catalyst is developed successfully. The PHF catalyst has good adaptability to feed stock, high desulfurization activity and stable activity and is industrially used in 10 sets of PetroChina’s diesel hydrofining units, with a total processing capacity aggregating to 17 million tons/year. The catalyst entirely meets the demand for production of clean diesel with the sulfur content less than 50µg/g or 10µg/g.
