200,000 tons / year diesel ultra-deep desulfurization industrialization device to drive a success
Recently, the research team led by Li Chan and Jiang Zongxuan, researchers from Dalian Institute of Chemical Physics, Chinese Academy of Sciences, devoted themselves to the research on the ultra-deep desulfurization technology of gasoline and diesel. On the basis of more than ten years of progress made in basic and applied basic research, The Group has collaborated on the development of a process and succeeded in driving a 200,000 t / y diesel hydrogenation unit at its Yongping refinery. China Petroleum and Chemical Industry Federation organized a panel of experts in the April 26 to 29 industrialized unit on-site 72 hours continuous operation assessment. The results show that the catalyst has high catalytic activity for hydrodesulfurization and can achieve ultra-deep desulfurization of diesel under relatively mild operating conditions. The operation of industrial plants is stable and all the indicators fully meet or exceed the contractual requirements. On the morning of May 28, "Development of Layered Multimetallic Sulfide Catalysts and Their Industrialization in Ultra-Deep Desulfurization of Diesel" held a fruit identification organized by China Petroleum and Chemical Industry Federation in Beijing. He Mingyuan, an academician of the Chinese Academy of Sciences, director of the Sinopec Ministry of Science and Technology Development, Professor Xie Xie senior vice president in charge of appraisal expert committee heard Yanzuo Petrochemical Deputy General Manager Luo Wanming's report, Dalian Institute of Chemical Li Chan's research report and industry Site examination report, conducted a lively discussion, gave a high evaluation of the technology, expert committee agreed that the identification of diesel ultra-deep desulfurization layered polymetallic sulfide catalyst with independent intellectual property rights, is a leading international level, agreed to be identified. The committee also suggested that as soon as possible to increase the industrial application of the technology to promote the technology to better serve our clean diesel production. Liu Zhongmin, deputy director of Dalian Institute of Chemical Physics, extended the chief engineer Hu Guangguang attended the appraisal meeting and made a speech. Ultra-deep desulfurization activity of layered polymetallic sulfide catalysts, the use of innovative preparation process, the layered metal compounds as a template, the use of environmentally friendly raw material route, the active ingredient and cheap metals into the interlayer obtained. The catalyst can be applied to ultra-deep desulfurization of straight-run diesel, straight-run diesel and catalytic diesel mixed diesel and catalytic diesel to meet the sulfur index requirements of the country V and the future VI diesel. The sulfur content of refined diesel products is less than 1mg / kg (less than 1ppm) when the mixture of straight-run diesel and catalytic diesel is mixed (mass ratio of 2: 1), and the desulfurization rate is more than or equal to 99.9%. Refined diesel product yield ≥ 99.4%. Total sulfur content of refined diesel, cetane number and polycyclic aromatic hydrocarbons indicators better than the national V diesel quality standards. This is the result of the successful application of the ultra-deep desulfurization of oil products with independent intellectual property rights achieved by the successful cooperation between Li Can and Jiang Zongxuan's research team and Yanchang Petroleum in Shaanxi Province. The success of steam and diesel ultra-deep desulfurization technology and their application in industry both have important practical significance for the upgrading of China's clean oil production technology, especially for alleviating atmospheric pollution and preventing haze. effect.
