    On June 21, the China Petroleum and Chemical Industry Federation organized authoritative experts in the industry to hold the Sanju Environmental Protection "MCT Suspended Bed Hydrogenation Complete Industrial Technology" (hereinafter referred to as "MCT Technology") appraisal meeting in Beijing.

    Hu Yongkang, Academician of Chinese Academy of Engineering, Yang Qiye, Academician of Chinese Academy of Engineering, Men Cungui, Professor-level Senior Engineer of PetroChina Consulting Center, Wang Zijun, Chief Engineer of Petrochemical Research Institute of China Petroleum and Chemical Corporation, Professor-level Senior Engineer Wu Qing of China National Offshore Oil Corporation, China Shi Xianping, Vice President of the Petroleum and Chemical Industry Planning Institute, Guan Minghua, Chief Engineer of Fushun Petrochemical Research Institute of China Petroleum and Chemical Corporation, Hu Changlu, Chief Expert of China Petrochemical Research Institute, and Bian Gangyue, Deputy Chief Engineer of China Petroleum Planning Institute attended the appraisal meeting .

    After listening to the project report, reviewing appraisal materials, on-site inquiries and replies, the participating experts agreed that the MCT technology independently developed by Sanju Environmental Protection reached the international leading level and passed the technical appraisal smoothly.

    Hu Yongkang said that China's first MCT suspended bed hydrogenation industrial demonstration device developed by Sanju Environmental Protection has been operating safely and smoothly for more than 500 days since it was first put into use in February 2016, marking that my country's heavy oil processing technology has reached the world's leading level.

    The only long-cycle MCT industrial device in the world The only long-cycle MCT industrial device in the world
    It is understood that the MCT technology is formed by Sanju Environmental Protection and Beijing Huashi United Energy Technology Development Co.
    , Ltd.
    (hereinafter referred to as "Beijing Huashi") It is independently developed by the team and is mainly used for the processing of heavy and inferior raw materials such as heavy residual oil and unconventional petroleum.

    Sanju Environmental Protection stated that through nearly 7 years of hard work, the R&D team has systematically carried out basic theoretical research, catalyst research and development, reactor research and development, key unit technology research and development, as well as small-scale test and pilot test verification, and comprehensively carried out industrial demonstration device technology research.
    It has overcome a series of major technical problems and built China's first MCT suspended bed hydrogenation industrial demonstration device with a multifunctional composite catalyst, high conversion rate suspended bed reactor, and complete unit process technology as the core.
    This technology has obtained 27 authorized patents (24 of which are invention patents).

    It is understood that the MCT suspended bed hydrogenation unit is located in Hebi, Henan.
    Since its first feed in February 2016, it has accumulated safe and stable operation for more than 500 days.
    It is currently one of the few industrial applications in the world that can operate safely and smoothly for a long period of time.

    During the operation of the device, different heavy and inferior oil products are processed to verify the raw material adaptability and reliability of the MCT technology.
    From December 17, 2016 to January 14, 2017, the Xinjiang naphthenic high-calcium heavy oil provided by PetroChina Karamay Petrochemical was processed.
    The data showed that the light oil yield increased from 60% of the traditional technology route to 90% , Which proves the advanced nature of the technology.

    From May 31 to June 3, 2018, 40% catalytic oil slurry + 60% intermediate base crude oil vacuum residue provided by Sinopec Jingmen Branch was processed.
    During the same period, the China Petroleum and Chemical Industry Federation organized experts The device was calibrated for 72 hours of continuous operation.
    The calibration results show that the conversion rate of >530℃ residual oil is 90.
    4%, the liquid yield is 88.
    3%, the heavy metal removal rate is 99.
    8%, and the conversion rate and light oil yield are at the international leading level.

    Overcoming the world's problems in heavy oil processing.
    Overcoming the world's problems in heavy oil processing.

    Global unconventional oil and gas resources mainly include 7 types of heavy oil, oil sands, tight oil, oil shale oil, shale gas, coalbed methane and tight gas that have been commercially developed.
    The total recoverable resources of unconventional oil and gas in the world are 583.
    4 billion tons, of which unconventional oil is 420.
    9 billion tons (accounting for 72.
    2%).
    Of the approximately 10 trillion barrels of remaining oil resources in the world, more than 70% are heavy oil resources.
    The efficient processing and utilization of heavy oil has become an unavoidable challenge for the global oil refining industry.

    In addition, the density, sulfur content, metal content, asphaltenes, and residual carbon values ​​of crude oil are getting higher and higher, and there is an urgent need for low-cost lightweight processing technology for heavy crude oil and its residual oil.
    At present, traditional refineries use fixed-bed residue hydrogenation, delayed coking and other technology to process heavy crude oil and its residue, which not only has a long processing flow and high cost, but also has low gasoline and diesel yields.

    Suspended bed hydrogenation technology is expected to solve the above problems systematically, so it has become the core technology developed by R&D institutions around the world and major international oil companies.
    As the key technology and equipment of suspended bed hydrogenation have not yet been effectively broken through and verified, the technology has not been substantively applied in the refining industry at home and abroad.

     Based on its own catalyst and purifier technology advantages, Sanju Environmental Protection and Beijing Huashi Qiangqiang jointly built a long-term safe and stable operation of the MCT suspended bed hydrogenation industrial demonstration device, which is not only a major breakthrough in the complete set of suspended bed hydrogenation technology, but also It provides a complete set of solutions for solving the worldwide problems of heavy oil processing.

    Experts at the conference said that, for example, the large-scale promotion and application of MCT technology can not only make the domestic residual oil be fully and effectively used, but also can import and process the cheaper products from the United States, Canada, Venezuela, Russia and other countries on a large scale.
    Regulating oil can save tens of billions of dollars in foreign exchange every year.
    Facilitating the upgrading of China’s oil refining technology is equivalent to rebuilding 1-2 large oil fields.
    At present, the overall level of China’s petroleum industry still has a certain gap compared with the world’s advanced level, and there is a lack of international competition in technology.
    force.
    The IEA report shows that China has invested a total of US$270 billion in the past few decades and has continuously invested in overseas oil and natural gas production to ensure national energy security.
     Experts at the meeting said that the major breakthrough in MCT technology has laid a solid foundation for the efficiency and technological upgrading of my country's oil refining industry.
     Traditional heavy oil processing technology routes generally require multiple process links such as fixed bed residual oil hydrogenation, wax oil hydrocracking/catalytic cracking combination, or delayed coking combination gasoline and diesel hydrofining.
    The use of MCT technology to process residual oil to produce clean gasoline and diesel can simplify the process and save investment.
    Taking 1 million tons/year of heavy oil processing as an example, the investment in MCT technology can be reduced by 10%-20% compared with the investment in traditional heavy oil processing technology routes.
     At the same time, traditional heavy oil processing technology has a low yield of gasoline and diesel, of which the yield of delayed coking gasoline and diesel is only 50%-55%.
    Using the MCT suspended bed hydrogenation complete technology, the gasoline and diesel yield can be increased by 20% or more on the basis of the traditional process, which is of great significance for improving the economic benefits of the enterprise.

           




    Data shows that my country's annual residual oil production capacity reaches 200 million tons.
    If all of this technology is applied, the annual output of gasoline and diesel can be increased by more than 60 million tons.
    In 2017, the domestic production of Daqing Oilfield was 34 million tons, and the annual oil and gas equivalent was 42.
    71 million tons.
    Therefore, if the MCT technology is promoted on a large scale, the annual production of light oil is equivalent to the discovery of 1 to 2 Daqing oil fields in China.

     Reducing the dependence on crude oil imports to ensure the national energy strategy security
    China is currently the largest crude oil importer, and its dependence on foreign sources is gradually increasing.
    CNPC Economics and Technology Research Institute released the "2017 Domestic and Foreign Oil and Gas Industry Development Report", stating that in 2017, the degree of dependence on foreign oil reached 67.
    4%, an increase of 3% over the previous year.
    Due to the decline in domestic crude oil production and the rapid increase in refining capacity, net crude oil imports continued to grow rapidly in 2017.
    The annual net imports were 420 million tons, a year-on-year increase of 10.
    7%.
    At the same time, China's self-produced crude oil dropped to 190 million tons.
    In the future, with the development of the national economy and the improvement of consumption levels, the total energy consumption will continue to grow, and the degree of dependence on foreign oil will further rise.

    It is worth noting that the technological progress marked by the complete set of MCT suspended bed hydrogenation technology has made unconventional petroleum resources an effective supplement to conventional petroleum resources.
    In particular, dense petroleum resources have good economic efficiency and are leading the petroleum industry.
    A revolution.

    Public information shows that unconventional oil is mainly distributed in the United States, Russia, Canada, Venezuela and other countries.
    Among them, Venezuelan super-heavy oil and Canadian oil sands bitumen are rich in resources, but due to their high density and high viscosity, pipeline transportation and storage are difficult, and direct export prices are low.
    If the MCT suspended bed hydrogenation complete set of technology is adopted, it can be light-weighted on the spot, solving difficult transportation and high processing costs, and can broaden my country's crude oil import channels and support the diversified supply strategy of crude oil.

    In addition, the complete set of MCT suspended bed hydrogenation technology can also be applied to the coal chemical industry.
    By processing coal tar and other by-products, it can guarantee the supply of domestic oil products, and realize the clean, high-value and efficient use of coal, creating a clean, high-value coal in my country.
    A whole new way to use.

    Experts at the conference pointed out that the successful breakthrough and industrialization of MCT suspended bed hydrogenation complete technology will play a positive role in accelerating my country's energy structure adjustment, reducing crude oil import dependence, improving national energy utilization, and promoting the leap-forward development of my country's industry.

    The scientific and technological achievement appraisal meeting was chaired by Hu Qianlin, deputy secretary general of the China Petroleum and Chemical Industry Federation, and relevant leaders of the federation participated in the technical appraisal.
