On June 19, the scientific and technological achievement of **Energy Group Chemical Company’s ‘Development and Industrial Application of SHMTO Technology for Converting Methanol into Olefins’ was successfully evaluated by the China Petroleum and Chemical Industry Federation. The appraisal committee unanimously agreed that this technology features advanced parameters and strong applicability; the overall technology has reached an international advanced level, with the large-scale MTO fluidized-bed high-efficiency reactors and quench water washing systems being at the international leading level. After listening to the work reports, research reports, novelty search reports, and summary reports on production and operation submitted by the project team, as well as the evaluation reports prepared by the evaluation expert group, and after reviewing the relevant technical documents, and following inquiries, defenses, and thorough discussions, the appraisal committee formulated a series of opinions: Starting from the synthesis of molecular sieves and research on catalysts, and going through laboratory studies, pilot-scale tests, and industrial application, this technology has developed into a new set of industrial technologies for methanol-to-olefins production, namely SHMTO, which includes both catalysts and process technologies ； A total of 70 authorized patents have been obtained, including 46 invention patents ； The MTO catalyst was put into industrial use in 2012; 6 MTO units were installed and deployed, with a consumption volume of over 9,600 tons ； The complete set of technologies was applied to Xinjiang Chemical’s 1.8 million tons per year methanol-to-olefins plant; the plant started up successfully on its first attempt in September 2016, entered commercial operation in January 2017, and has been operating steadily for over three years. It is reported that Shenhua’s methanol-to-olefins technology suite represents another major industrial application technology with complete independent intellectual property rights, following the coal direct liquefaction technology suite; it provides strong support for the development of the chemical company’s core industries.
