[Reported by Reporter Li Huadong and Correspondent Song Xuejuan from Beijing] http://www.sxycpc.com/ycinfo.jsp?urltype=news.NewsContentUrl&wbtreeid=1012&wbnewsid=57417 On September 15, the industrial-scale technology for co-processing kerosene (Y-CCO), independently developed by Yanchang Petroleum Group, passed a technical evaluation organized by the China Petroleum and Chemical Industry Federation in Beijing. The experts present believed that this technology is highly innovative and is generally at the world’s leading level; it holds significant strategic importance for the clean and efficient conversion of coal resources, reducing dependence on petroleum resources, and ensuring **energy security. “Through more than 4 years of systematic research, pilot tests, and operation of industrial demonstration plants, we have developed a complete set of industrial technologies for kerosene co-refining (Y-CCO). ”He Jiuchang, chairman of the group company, said. Since the launch of experimental research on kerosene co-refining technology in April 2011, building on domestic and international research into slurry-bed (also known as suspension-bed) hydrocracking technology, Yanchang Petroleum has actively pursued the introduction, assimilation, and further innovation of such technologies, carrying out a series of new technology developments, process improvements, and engineering integration innovations. In September 2014, the world’s first industrial demonstration plant for the co-processing of kerosene with a capacity of 450,000 tons per year was built in Jingbian, Yulin. It began operational trials in January this year, with the entire production process successfully established ； In mid-August this year, the China Petroleum and Chemical Industry Federation organized experts to conduct an on-site assessment of the facility’s 72-hour continuous operation. The results showed that at a coal powder concentration of 41.0%, the coal conversion rate was 86.0%; the conversion rate of the catalytic cracking slurry at temperatures above 525°C was 94.0%, the liquid yield was 70.7%, the energy conversion efficiency was 70.1%, and the water consumption per ton of product was 1.6 tons. The appraisal committee, composed of 15 renowned experts from China’s energy and chemical industry including academicians Yuan Qingtang, Wang Xieqing, Yang Qiyeh, Hu Yongkang, Shu Xingtian, Li Can, and Li Hongzhong from the Chinese Academy of Engineering and the Chinese Academy of Sciences, concluded that Yanchang Petroleum’s industrially applicable technology for co-processing coal (Y-CCO), which is developed for the first time and uses medium- and low-rank coal as well as heavy (poor-quality) oil as raw materials, employing an online integration of slurry-bed hydrocracking and fixed-bed hydrocracking to produce light oil products, is highly innovative and overall at the world’s leading level. The innovation lies in the proposal of a synergistic reaction mechanism for kerosene co-refining, as well as the first development of an industrial online integrated process combining slurry-bed and fixed-bed hydrogenation, which provides a foundation for the development and application of kerosene co-refining technologies ； A proprietary catalyst-additive system for kerosene co-processing was invented, which provides more active hydrogen and effectively suppresses coking reactions, thereby achieving high conversion rates and high liquid yields from coal with high inert content as well as heavy oil. Meanwhile, the precursors of coke deposit mainly on the surface of the additives, alleviating the coking problems in the reaction and separation systems ； A technology for underwater molding and modification of coal-based asphalt sand was invented, which solved the problem of inability to mold the material due to fluctuations in its softening point; it also prevented light hydrocarbons from volatilizing and contaminating the environment, thereby expanding the application areas of coal-based asphalt sand ； A specially designed thermal insulation lining and inner cylinder for slurry bed reactors were invented, addressing the challenges related to material selection and installation of thermal insulation materials under conditions of high temperature, high pressure, and exposure to hydrogen ； The use of a liner tube with a simple structure prevents coking on the reactor wall. The appraisal committee agreed that the technology has passed the appraisal and recommended accelerating its promotion and application. Li Yongwu, President of the Third Council of the China Petroleum and Chemical Federation, attended the technical appraisal meeting and delivered a speech. Shen Hao, Secretary of the Party Committee of the group company; He Jiuchang, Chairman; Yang Yue, General Manager; Zhang Jiyao, Senior Advisor; Luo Wanming, Chief Engineer; and Li Dapeng, the lead expert on the project for the in-depth transformation and utilization of coal by different grades, attended the appraisal meeting. Li Yongwu believes that at a time when oil prices continue to fall and the coal chemical industry is at a critical juncture in its history, the successful development of industrial technologies for co-processing coal and kerosene has improved the efficiency of converting coal and heavy (low-quality) oils. It opens up a new pathway for producing oil from coal, and holds great practical significance for leveraging China’s coal resource advantages as well as for developing the oil production industry and converting heavy (low-quality) oils into lighter forms. These technologies have promising prospects for application and dissemination; therefore, efforts should be made to further refine them and optimize the processes, in order to accelerate their technical and market adoption. It is understood that this technology overcomes the technical challenges in two areas: the clean and efficient conversion of coal in the coal chemical industry, and the upgrading of heavy (low-quality) oils to lighter forms in the petrochemical industry. It not only addresses some of the shortcomings of direct and indirect coal liquefaction but also provides new process solutions for the processing of heavy and low-quality oils as well as coal tar in refineries. This approach fosters a technological integration between heavy oil processing and modern coal chemistry, opening up a new technical route for coal-to-oil production and the upgrading of heavy (low-quality) oils in China. It holds great potential for widespread application and industrialization. Based on the Y-CCO integrated industrialization technology, Yanchang Petroleum has filed 27 patents, of which 10 have been granted.
